The penis ring FLAME made of 100% medical-grade silicone is pulled over the penis to the base. It increases the build up of blood in the penis, boosting the hardness and duration of an erection. FLAME is extremely flexible – and can easily and safely be removed at any time. Putting on the FLAME works best with a few drops of water-based lubricant (TOYFLUID). The “flames” which give the toy its name not only represent hot sex, but are practical to stimulate the partner’s clitoris during sex.
