KINK3D products are made from 3D-printed nylon. The material is a smooth, rigid, lightweight plastic.

The products are shower-safe, can be worn in hot tubs and swimming pools, and are compatible with water, oil, and silicone-based lubricants.

A small amount of dye may come off new KINK3D products. The dye is skin-safe, and excess dye generally stops after a few days to a week.

Clean with soap and warm water or isopropyl alcohol. Boiling is not recommended and may damage the material.

KINK3D products are designed in California and manufactured in the USA, so we know exactly who makes them, and can trust that they are made to the highest standards.
Yes. All KINK3D base rings are interchangeable with all Cobra cages and 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, and they are smooth out of the box.

The lock opening 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 whole device would have to be larger and less discreet under clothes.

Also, a lock opening on the left makes it easier for all the right-handed keyholders out there :)

As Henry Ford supposedly said, Cobra cages are available in any color, so long as it is black :)

A small number of Cobra cages in other colors were made as a test in the past, and you may see photos of them online from time to time. 

We are working hard to officially launch more colors using advanced new additive manufacturing technologies. We'll announce these on our social media (r/kink3d, @kink3ddesigns) and add them to our lineup here at as soon as they're ready. Thanks for your patience!

We continuously work to improve the safety of our products. That includes a focus on ergonomics, pinch points, sharp edges, and rough texture. We believe they 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 extremely unlikely event that a device gets stuck on you, try using soap or lubricant to help slide it off. If that doesn’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. The sensitivity is usually noticeable quickly. If you experience a reaction, we suggest that you stop using the product right away, and symptoms should cease within a few days to a week.

KINK3D products in colors other than black are hypoallergenic, and we are not aware of any reports of skin sensitivity.

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 secure a penis in a ball trap device is to use a penis piercing, like a PA.

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.

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.

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.

We've shipped our cages to over 30 countries, and the list is growing!

Please double-check the VAT and/or customs for your country before ordering. We don't want anyone to be surprised. These costs are entirely beyond our control.

We do not have any way to collect these charges in advance. The shipping service (UPS, DHL, or your local postal service) will often contact you to pay for the VAT/customs before they deliver your package.
