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.

Products can be sterilized with a brief soak in isopropyl alcohol (15 min). Some dye may come out in the process.

Boiling will not melt PA12 nylon, but regular boiling 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.

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 lock would rotate backwards instead of forwards, and the whole device would have to be larger and less discreet under clothes. It would also prevent use of the KINK3D Airlock.

Lastly, we're fans of the extra consequence that 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 smooth textures. We believe our 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. 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 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.

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.

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.

Due to the intimate nature of our products, we aren't able to offer returns/refunds or exchanges for a different size.

However, if you receive your order and discover a problem such as a defect, missing item, or wrong item, please get in touch as soon as possible, and we'll sort it out for you!

We also want people to be aware of the secondhand marketplace for KINK3D products at r/KINK3Dexchange. It's a great place to find new sizes at a discount, trade sizes, or connect with buyers for sizes in your collection that you may not be using anymore.

KINK3D products are currently available at Chez Priape in Montreal, QC Canada. We hope to add more retail partners soon. Check our Official Partners page for updates.

We send orders out as fast as possible, but we're still a small business. Orders generally ship in 1-3 business days, though occasionally can take up to 2 weeks.

We offer several shipping speeds at checkout. Please note that estimated shipping time is for actual time in transit. It does not include the time required to get your order ready.

Please also note that estimated shipping times are estimates. They are not guarantees. In our experience, the vast majority of packages arrive safely and quickly, however some packages are delayed during transit and can take extra days or weeks to arrive. We greatly appreciate your patience when this happens!

We've shipped our products 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. This charge may include a brokerage fee, which is the cost charged by the carrier to process your order through customs.
