The surface of a starfish is raised, and the inside is ribbed, giving extra pressure and amazing stimulation to the perineum. The collar fits the bottom of the penis and gently restricts blood flow. This allows you to experience a larger, harder, and more satisfactory erection. The ball ring surrounds the bottom of the scrotum, which provides additional support while helping you grow longer and stronger.[Double Ring] This elastic silicone reinforced ring can lift your penis and testicles. The double loop ring surrounds the rod and the ball, creating a tight fit that not only increases endurance, but also achieves a larger and harder erection.
