Created for serious chastity players, the innovative CB-X male chastity devices are built for total security and maximum comfort. Their unique design consists of three parts that fit together like a puzzle, with spacers and a range of ring sizes that help to create a custom fit that suits your personal needs. The Curve is the largest CB-X model, with a 3.75 inch long cage with an ergonomic shape that provides a comfortable, natural fit, vented sides for hygiene, and a bottom opening for urination. It comes with five sizes of U-ring that range from one-and-a-half to two inches in diameter, with a flat shape designed to promote comfort even during long-term wear.

The cage is made from medical grade polycarbonate, a material that is lightweight, hypoallergenic, and durable. This model is transparent. The cage can be locked in place using the included brass padlock, or the numbered plastic locks, which are ideal for discretion during air travel. A handy drawstring storage bag is included.
