A look at what I thought of the KINK3D Cobra N after a shorter-than-expected wear-test period.
Because I’m now locked by a keyholder, I had to cut short my wear-testing of the KINK3D Cobra N. My keyholder insists I use a device that can be secured with disposable plastic numbered tag and other alternatives are not up for debate.
Since we have only just become acquainted, I understand and respect her opinion on the matter. So, I replaced the Cobra N with one of my stainless steel devices that allows the use of the plastic locks. Still, with only a few days of wear, I feel confident I can already express an honest opinion on this KINK3D authentic Cobra device.
First Impressions of the Cobra N
I chose the Cobra N model to review for two reasons. First, it is the same size as my Badassworkroom HF-001 E1B, the shorter version of the two Badassworkroom devices I have that are patterned on the Cobra. The difference is the Cobra N is 3D-printed, while the Badassworkroom devices that copy the Cobra design are molded resin devices. Interestingly, the Badassworkroom has discontinued offering the HF-001 devices and they are no longer available from the main website or its Etsy store.
The other reason I chose the Cobra N is because it is the shortest cage KINK3D offers with the “wide girth” option. I wanted that instead of the standard size (similar to my HF-001 E1B) because I have a thicker than average flaccid penis. And I’m happy I chose the wide girth option because while my flaccid penis still fills the space, it feels so much more comfortable and less restrictive. KINK3D offers one shorter cage version called the Baby Cobra, but the wide girth isn’t available with that device. Otherwise, I would have felt tempted to order the Baby Cobra instead.
I loved the smooth tactile feel on my fingertips of the Cobra right out of the box. Although I truly like the Badassworkroom copies I have, the texture of the Cobra feels silky smooth in comparison. And it felt exactly the same when I put on the device for the first time. It fit like a glove and was so lightweight that it was virtually unnoticeable.The standard 3/8 inch gap works perfectly for my high and tight scrotum. I also liked that I could wear the Cobra comfortably with the base ring that most closely matches the size I use with my custom-made stainless steel devices.
Cobra N Specifications
Unlike other chastity device manufacturers, KINK3D does not publish size specifications on the lengths of its device cages. Possibly this is aimed at preventing other manufacturers from copying their exact designs. Instead, they recommend cage size based on the users’ flaccid penis measurements.
As an example, the company recommends the Cobra N for those with flaccid lengths from 2 to 2-1/2 inches. Flaccid length varies near constantly because of environmental factors, variations in resting blood supply to the penis, hormonal activity, etc. As I have shared before, my flaccid varies from 2.5 inches to a little over 3 inches and I find the Cobra N still fits me perfectly. Just about anyone with a flaccid size, even well over 2-1/2 inches, could wear the Cobra N comfortably since “turtling” would take care of any excess length. But KINK3D offers the Cobra in eight sizes to accommodate flaccid sizes from 1.25 inches (Cobra Baby) to 6 inches (Cobra BFG). Consult the KINK3D website if you are interested in learning what size the company recommends for all the length ranges.
Cage Inside Diameter
KINK3D also does not reveal the exact internal diameter measurements for its cages. Instead, the company suggests its three available internal diameters based on flaccid penis girth.
They recommend the “Narrow” option for those with thinner than average flaccid penises (available with the Baby, N+, and S models). The company recommends the “Standard” option (available with all models) for those with flaccid penises of average girth. The third option, “Wide” (available with N, N+, S, S+, R, and R+ models), is aimed at those with thicker than average flaccid penises. Standard works for most individuals and is the place to start unless you know from experience with other devices that Narrow or Wide would suit you better.
Base Ring Sizing
KINK3D offers no specific advice on measuring for base ring size. Instead they tell you to rely on your past experience with other devices or advise you to consult existing references available on the web. So, knowing my ideal base ring size is 43mm, I chose the KINK3D Nubmber 2 base ring, which is minutely larger at 44.5mm and fits well.
I won’t reprint the list here for the sake of brevity, but KINK3D offers eight different base ring sizes that range from 1-1/2 inches (38.1mm) to 2-3/8 inches (60.3mm). You can review all the available sizes here on the company’s website.
The company also offers three different styles of base rings:
XD – thicker than the standard 8mm rings and recommended for those with smaller testicles or who need a narrower gap between the base ring and cage.
Standard – 8mm thickness and works for most people.
Curved – 5mm backward curve at the bottom. The curved ring is good for troubleshooting pressure under the scrotum. But KINK3D warns that people with smaller testicles can be more likely to pop a testicle out through the wider gap.
I purchased an extra ring with my device because I wanted to try the curved ring. Pressure under the scrotum is the only discomfort I ever have with any chastity device and is especially pronounced when my cremaster muscles are intent because of environmental conditions on pulling my testicles up and closer to my body. My testicles are average size, not small, but with the curved ring, my right testicle kept popping out of the base ring. The curved ring eased all the pressure under my scrotum, but is unusable since my right testicle refuses to cooperate. The standard ring of the same diameter works perfectly. My recommendation is to stick with the standard base ring.
Security of the Cobra N
Cobra devices are standard “ball-trap” devices, and no ball-trap device is escape proof. While KINK3D claims a well-fitted Cobra minimizes the chance of escape, I must tell you the truth. The Cobra has the same security flaw as all the Cobra copies I’ve tried before testing the actual Cobra.
By placing a thumb between the integral lock housing and my abdomen and pushing outward, I can easily push the ring and cage away from body until I expose almost half of my flaccid penis length. Then, using the index finger of my other hand, I can easily back my soft penis out of the cage and out the back of the base ring. Once my penis is free of the device, my right testicle easily comes out of the base ring and then the left testicle comes out and I’m free of the locked device.
If I did not remove my testicles from the base ring, I could push my soft penis back inside the cage. But when I removed the device completely, I could not put it back on without unlocking it. That means a wearer could back their penis out of the locked device, and while leaving their testicles inside the base ring, masturbate to orgasm, and then put their penis back inside the cage after becoming flaccid again.
So, for those willing to cheat a keyholder (and themselves), the Cobra does little to prevent it. Still, for those who are serious about chastity and ethical enough to keep their commitments to a keyholder, the Cobra offers adequate security. It definitely will not fall off by itself. But as one example, the Holy Trainer devices offer far more deterrence against cheating than the KINK3D Cobra devices.
PA Piercing Compatibility
KINK3D states the Cobra is generally compatible with PA piercings. This is the FAQ information they have published on the website to the question, “Are Cobra cages compatible with a Prince Albert (PA) piercing?”
“Generally yes. PA piercings up to 2 gauge size should be compatible with all standard Cobra cages (with the exception of the Baby Cobra Narrow, which can only accommodate 6 gauge PAs and smaller). PAs that are 0 gauge or larger may fit on certain cage sizes, but can be a tight squeeze.” (Source: https://kink3d.com/apps/help-center#hc-do-you-make-your-cages-for-people-with-a-pa).
However, I’ve read several reviews written by individuals (including Thumper) who have PA piercings and have tried the Cobra devices who all say that while the devices work with PA piercings, they often experienced instances of unpleasant pinching. So, this device may not be the best option for those with a PA.
Yes, I'm back in black
One thing I loved about Badassworkroom HF-001 Cobra copies were the vibrant colors the company offered. I have one in a light purple color and one in hot pink. In comparison, KINK3D offers the actual Cobra in black only. Information on the website suggests they are testing dyes and may offer additional colors in the future, but that information has been published for a while now, so I’m unsure how committed they are to the idea.
Pricing Considerations
The KINK3D Cobra devices are not the priciest plastic devices on the market, but they are not cheap. That explains why so many people opt for buying the less expensive copies from other manufacturers. Prices range from $160 (Cobra Baby) to $200 (Cobra BFG) for the full kits that include one base ring, the cage, and the integral lock with two keys.
I paid $170 for the Cobra N plus another $40 for the extra curved base ring. KINK3D sells cages and base rings separately. If, for example, I wanted to try the Baby Cobra, I could just buy the cage and use it with the base ring they came with my Cobra N. But the component pricing is also pricey. If you bought a cage and a base ring separately, the combined cost would equal the price of buying a complete kit, only you would not get a lock with it.
Since I’m not in the business of manufacturing 3D-printed chastity devices, I don’t know what it costs to produce a Cobra. But I have a fake Cobra I purchased from eBay about a year ago which is 3D-printed, came with four different sized base rings, and cost me less than $30. It is a very faithful reproduction, so much so that the base rings fit my actual Cobra N perfectly. And both devices have the same silky feel regarding finish and how they feel when wearing them. That leaves me wondering how much of the KINK3D prices represents profit. 3D printers are not inexpensive, so I know they have some sunk costs, but I think their prices are higher than necessary. Especially now that many options for quality 3D-printed chastity devices exist.
Frankly, I like the Cobra N device and find it comfortable to wear. But in comparison, I consider my Holy Trainer Nub, a comparable sized device that was $5 cheaper, a far superior device in almost every way. Except for my interest in reviewing the Cobra, I doubt I would have ever paid $170 for a Cobra N, especially since I already have the Badassworkroom copy that performs identically.
That said, now that I have the Cobra N, I know I will wear it often. In fact, I just ordered the KINK3D accessory called the airlock, which is a metal-free lock adapter you can use with disposable numbered plastic locks in place of the standard lock. No more worries about metal detectors when you travel and in my case, I hope my new keyholder will allow me to wear the Cobra N with the airlock and a plastic lock since I don’t like wearing my stainless steel devices secured with plastic locks since they allow the cages to rotate excessively on the locking pins.
Hygiene Concerns
The one area in which the Cobra N outshines the Holy Trainer Nub is ease of cleaning while wearing it. Since it is an open-type cage style device, I found I can clean it just as easily and thoroughly in the shower with my handheld shower head as any of my stainless steel open cage devices. That means I can wear it indefinitely with no need for removing it for cleaning as I must do with the closed tube Nub.
The Verdict
I think the KINK3D Cobra devices are a little pricier than necessary since they are basic plastic ball-trap devices, and the devices provide less deterrence to cheating than other plastic devices of comparable quality and price. But I have no other criticisms as the Cobra is a high quality, made in the USA device that is comfortable to wear and will not injure the wearer provided the person takes the time to measure and gets a properly fitted device. And as soon as I receive the airlock accessory, I hope to persuade my keyholder to allow me to return to wearing the Cobra N.
PROs
- Excellent quality
- Silky smooth feel

Disclaimer: This review represents my honest opinions and as always I purchased this device at the advertised retail price using my own funds. I have no affiliation with KINK3D except as a satisfied customer.
In the next post, I will share a little about my new keyholder. We met on a video call for the lock up and she quickly removed any doubts I might have had about her sadistic nature. I’m still applying a frozen bag of peas today between my legs. But it was worth it because I got to actually see her and learned that she is impossibly attractive and projects her authentic dominant nature even virtually. I may have found the keyholder of my dreams.
