This stretchy silicone set contains one soft (player) and one hard (trainer) which can be used as cock rings or ball stretchers. For use as a ballstretcher, use the softer of the two with nubs on the outside and you get the feeling of a silicone ball stretcher with a firm, pliant grip for regular-player possibilities. Turn it inside out and the nubs will grip like neoprene for player-inside out possibilities. Use the harder ball stretcher for trainer-regular and trainer-inside out possibilities. Available in Black.
