A fantastic set of penis rings offering five distinct size possibilities, this enhancer combo from TitanMen easily accommodates just about any pleasure whim, not to mention any size man. Made from soft, ultra-stretchy jelly, the chosen ring will snugly surround the base of the penis and testicles (or just the base, if you prefer) when in place, keeping a tight hold on blood flow and in turn, creating a firmer erection. Each ring features easily maneuvered side tabs for easy removal and adjustment, the stretch-to-fit styling is extremely simple and great for beginners. Speaking of which, the general rule of thumb is to start with the larger ring and work your way down, as the smallest ring will provide the most intense hold. Compatible with both water and silicone-based lubricants. Phthalate free. Measurements: - Rings measure 0.4" to 0.
