By performing the same basic function as a penis ring, but wider and more robust, the reliable TitanMen Cock Cage allows you to stay harder plus adding more volume. The envelope is stretchy, with a ribbed texture for improved stimulation for your partner and provides a comfortable tightness for your member. Made of TPE with Doc’s antibacterial Sil-gel formula, this Cock Cage is phthalate-free and safe for the body. We advise you not to wear it for more than 20 minutes at a time.
