Products

KINK3D products are made from 3D-printed PA12 nylon. The material is a rigid, lightweight plastic.
After printing, the products are finished with an industry-leading vapor process, which smooths them and seals the outer surface.

A small amount of dye may come off new KINK3D products. Excess dye generally stops after a few days to a week.

KINK3D products are designed in California and manufactured in the USA.
KINK3D products are shower-safe, can be worn in hot tubs and swimming pools, and are compatible with water, oil, and silicone-based lubricants.

We recommend regular cleaning with soap and warm water, including gentle scrubbing of interior surfaces with fingers or a soft brush or cloth.

Products can be wiped or sprayed with most common cleaners, or more thoroughly sterilized with a brief soak in isopropyl alcohol (~15 minutes). Some dye may come out when soaked. Boiling will not melt PA12 nylon, however boiling frequently or for long periods may degrade the material or fade the color and is not recommended.

Yes. All KINK3D base rings are interchangeable with all Cobra cages and KINK3D shaft rings. This means you can mix and match sizes and styles to get your fit just right. Plus, any additional rings or cages that you order will fit the pieces you already own.
No. All KINK3D products use an advanced post-processing technology after 3D printing, and they are smooth out of the box.

KINK3D cages and base rings are designed to fit together snugly. This reduces the chance for skin to get pinched. It also helps prevent motion that can allow the balls to slip through the gap and escape.

Due to minor variations in 3D printing, certain cage/ring pairs can fit together more snugly than others. This is normal for the manufacturing. If your device is difficult to attach at first, it may require breaking in. Firmly press the cage and ring together until the two side pins on the cage are fully seated in the slots on the ring. Then let the device sit for 24-48 hours. Assembly should get easier after this break-in period.

Occasionally it can be difficult to push the metal lock all the way into the lock chamber. First, double-check that your cage is fully seated in the ring. If even 1 mm of the side pins isn’t pressed into the slots, it can prevent the lock chamber from aligning. Once the pieces are fully seated, press the lock firmly into the chamber, remove it, and repeat several times. You may notice thin flakes of nylon plastic being shaved off by the sharp edge of the metal lock during this break-in process.

If you still have trouble connecting your device, please contact us at [email protected] and let us know. We may ask you to supply a picture or short video clip to help us diagnose the issue.

KINK3D products can sometimes fit together snugly. If your device has a tight fit, it may be difficult to pull the cage straight forward off the base ring. Instead, pull the cage off the base ring at a slight angle, alternately pulling one pin at a time (left pin, right pin, left pin, right pin…).

You should be able to “wiggle” the cage off the base ring using this method. It can be much easier than pulling straight out away from the base ring.

The opening for the lock is on the left side of the device because of the direction the key turns in the lock. If the opening were on the other side, the lock would rotate backwards instead of forwards, and the whole device would have to be larger and less discreet under clothes. It would also be incompatible with the KINK3D Airlock.

As a bonus, this makes it easier for all the right-handed keyholders out there!

However, the Airlock can be fiddly to put on. It gets a lot easier with practice, but if you’re still having trouble, you can follow this short tutorial video (SFW) to learn how to assemble the Airlock backwards. This trick makes it much easier!

All current KINK3D cages are engraved with their size under the lock area. In addition to the length marker, you may see a dot to the left or right. Dot on left: Narrow. Dot on right: Wide.

For example, the Cobra N+ Narrow is marked like this:

KINK3D Base Rings are marked on the front side, at the top, under the lock chamber. For example, a Size 1 Base Ring is marked like this:

Note: Some older versions of KINK3D products may be unmarked.

When KINK3D first started out, their cages were called the KINK3D X-Lock Cobra. That was quite a mouthful, and in 2021 they simplified the name to KINK3D Cobra. However the original name lives on in the trademark ‘X’ engraving on the back of thebase rings!

Safety

KINK3D continuously work to improve the safety of our products. That includes a focus on ergonomics, pinch points, sharp edges, and smooth textures. We believe their products significantly exceed the industry standard.

Ultimately, KINK3D products are use-at-your-own-risk. If you experience any medical issue such as restricted circulation, bruising, or skin irritation, please — at minimum — take a break from the product and reevaluate sizing. If your symptoms persist or are severe, please seek medical attention.

When you first receive your device, test it slowly. Do not immediately give your key to another person who lives far away from you. It can take at least several weeks to make sure the device is suitable for longterm wear.

In the unlikely event that a device gets stuck on you, try using soap or lubricant to help slide it off. Taking a hot shower will also warm the material, which slightly increases its ability to flex. If those methods don’t work and you don’t feel that you can safely break it, go to a doctor. However embarrassing it is, we promise, they’ve seen worse.

Black KINK3D products are colored with a skin-safe dye containing paraphenylenediamine (PPD). PPD is widely used in hair and beard dyes, as well as in consumer clothing.

A small number of people exhibit skin sensitivity to PPD. The sensitivity is usually noticeable quickly and can include itchy skin and/or inflammation. If you experience a reaction, we suggest that you stop using the product right away, and symptoms should cease within 1-2 weeks. Please consult a doctor if symptoms are severe or persist.

KINK3D products in colors other than black are hypoallergenic. While we can’t guarantee individual outcomes, in our experience reactions are extremely rare.

Chastity

We get this question a lot. While it is true that chastity fans often seek out smaller cages over time, this is mostly for the fun of being more snugly contained. We are not aware of any research showing that chastity devices cause lasting anatomical changes to the penis.
KINK3D chastity devices use the “ball-trap” method, and no ball-trap device is foolproof. A well-fitted device should minimize the chance for escape, but the only way to fully secure a penis in a ball-trap device is to use a piercing, such as a Prince Albert (PA), to actually lock the head of the penis to the bars of the cage.

Sizing

We base our cage recommendations off of your normal smallest flaccid length.

When measuring flaccid length, allow the penis to hang naturally. Measure along the top side of the penis from base (where it meets the body) to tip. It’s best to use a cloth tape measure, or a string which you can measure with a regular ruler or tape measure. We suggest measuring several times over the course of the day under “normal” conditions — not right after a hot shower, and not when it’s extremely cold.

More detailed instructions can be found in our Cobra cage sizing guide.

Unlike other chastity brands, we don’t recommend trying to measure for base rings. We’ve never found a reliable way to get good numbers and when people do measure, they often get results that are way off from what they need.

If you have experience with other chastity devices that use circular and flat (not curved) rings, the base ring inner diameter should translate to a similar KINK3D base ring. If you have experience with other types of base rings, or need additional help, feel free to email us or check out our base ring sizing guide.

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.

If you have questions about your PA and a specific cage, you can email us.
