The Curve Male Chastity Device is designed for the larger male. The Curve is newly updated to incorporate the larger cage of the classic Curve model and the innovative ring design of the CB-6000. The rings consist of three interlocking pieces that fit together like a puzzle. The two guide pins hold the top pieces together. The oval locking pin goes through the middle recessed hole connecting the cage portion to the ring. The flat design of the rings is extremely comfortable and secure. The Curve is made of medical grade polycarbonate material. It is lightweight, hypoallergenic and durable. The cage portion is vented for hygiene and has a bottom opening allowing use at urinals. The different size rings and spacers included in each package allow you to customize your fit to your individual needs. The Curve restricts you from touching your genitals for sexual pleasure and gives the Keyholder control over the sexual fulfillment of both partners.
