Product details
Please note that if you want a base ring, you must specify the style and size as all components are separate.
Welcome to KINK3D COBRA, where you'll discover total comfort so you barely know it's there except when you're reminded. Each piece is 3D printed in the United States using aerospace grade manufacturing.
When measuring flaccid length, allow the penis to hang naturally. Measure along the top side of the penis from the base, where it meets the body, to the tip. It is best to use a cloth tape measure or a piece of string which can then be measured using a standard ruler or tape measure.
We recommend measuring several times during the day under normal conditions, not immediately after a hot shower and not when it is extremely cold.
The goal is to find your typical smallest flaccid length rather than the absolute smallest size you ever reach.
The advice on this page is a best guess. Everyone’s anatomy is different and results may vary.
Length Advice
In our experience, customers are happiest when their Cobra cage closely matches their natural flaccid length. If the cage is too short, it may hang away from the body and only partially cover the shaft. If the cage is too long, the head of the penis may not sit correctly in the head section of the cage.
Getting a new chastity cage can be exciting, but it is important that you are not partially aroused when taking your measurements. This can lead to overestimating your size.
If you are between two sizes, most customers tend to prefer choosing the slightly shorter cage.
Width Advice
The Standard width works well for most users. If you have a thinner than average penis or have found other devices loose in the past, the Narrow option may be a better fit. If you have a thicker penis or have struggled fitting into other devices, the Wide option may be more suitable.

KINK3D Cobra fit guide
Get the fit right.
Cobra has an open, tapered profile for maximum airflow, easier cleaning and a more held-in-place feel through the head section.
Cage width
Standard suits most people. Choose Narrow if cages usually feel loose, or Wide if they normally feel tight.
Base ring
Use a KINK3D ring you already know is comfortable. If you are starting fresh, #2 and #3 Standard are the common trial options.
Package
Choose Cage Only if you already own compatible parts. Full Kit includes your cage, base ring, lock and two keys.
