Cobra & Viper
Two iconic styles.
Cobra
We launched the KINK3D Cobra® in 2019. It quickly gained notice in the chastity world, combining ultra-lightweight & durable 3D printing with forget-it's-there comfort and a sleek biomorphic design.
Features
• Our airiest, most open design. Cleaning is a cinch.
• On most sizes, Cobra tapers from a wide entrance to a narrower head ring, with a distinctly flared head.
What to know
Cobra's shape is more like a circumcised penis. Cobra wearers are often happiest when the head of their penis sits inside the head section of the cage. This accentuates the glans while keeping things lined up for daily wear.
But that doesn't mean Cobra is just for cut cocks. Many chastity fans with foreskin love Cobra too, especially for its ease of cleaning. If you're uncut, just be sure to check the head ring measurement before ordering to ensure that it won't squeeze down too tightly on your foreskin. Due to the narrowness of the head ring, we find that some uncut wearers prefer to size up to the Wide models on Cobra, to give the foreskin some extra room.

Viper
In 2024 we released our second cage line, the KINK3D Viper®. Instantly recognizable as a KINK3D creation, but with a style that's all its own, Viper combines armored protection for your package with sweeping curves.
Features
• More enclosed. Fully closed underside and shielded head. All while retaining longitudinal slits for ventilation and cleaning.
• New geometry with consistent inner diameter. The width on Viper stays (almost) uniform throughout the length of the cage.
What to know
Viper is shaped more like an uncircumcised penis — but it's a hit with everyone!
Viper features a more consistent inner diameter. Unlike Cobra, it isn't designed to lock the head of the penis in place. Rather, it is normal with Viper for the head of the penis to fit partly inside and partly outside the head section of the cage. This lets the penis slide back and forth more easily as it naturally moves and changes shape throughout the day.
For uncut wearers with a more delicate foreskin, Viper has fewer openings where skin can get pinched between the bars of the cage.
Uncut wearers may also find that Viper's wider "neck" behind a shorter head section helps reduce the chance of foreskin edema. Customers with lots of foreskin and/or a very thick penis may be able to fit comfortably into a Viper cage when they couldn't fit into Cobra.
Compared to Cobra, Viper cages in Wide are truly large — especially in the R, R+, and BFG sizes. Please review their measurements carefully.
