This cock ring set has three rings attached to each other: a 2 cm diameter ring, a 3 cm diameter ring and a 4 cm diameter ring. The largest ring (4 cm) is worn around the scrotum. The second ring (3 cm) should be placed around the testicles. The smallest ring (2 cm) should be placed around the penile shaft. The use of a cock ring restricts blood flow and allows the user to have a fuller and harder erection. The cock ring around the testicles keeps them from contracting, prolonging the orgasm.
