New for 2025, KINK3D Arctic White products are 3D printed in the US from dye-free, high-density PA12 nylon, using advanced machines developed for the biomedical industry. They are finished with the same vapor solvent as our classic black cages, giving them a satin-smooth, nonporous surface. For a complete device, you need a KINK3D Cobra® cage, a base ring, and a lock to connect them. To order all three parts together, check out our Cobra R+ Kit, where you can select your base ring and get a standard lock thrown in for free! All KINK3D chastity cages and base rings are interoperable. If you already have the perfect base ring, and you're looking for a Cobra R+ cage by itself, then this is the right page. Arctic White pieces may contain ultra-thin filaments embedded beneath the surface. These can appear as fine strands or miniature colored spots and give each piece a unique signature. Sizing The Cobra R+ cage is suggested for a flaccid length of 5-5.5" (12.5-14 cm). The Cobra R+ cage also comes in two different versions: Standard and Wide. We find the Standard works well for most people — but if you need some extra room, then the Wide may be just right for you! For sizing help before ordering, please review our size guide for Cobra cages, or email us for personalized sizing advice.
