Nasstoys Enhancer Silicone Cockties are a best-selling classic favorite! These very stretchy rings are fully adjustable by sliding the round ball up or down, allowing the user to adjust to the perfect fit!  The hollow interior disperses the pressure for comfort and helps the ball from sliding so the ring stays in place!  One black and one red come in each clam-shelled pack.  Clean with toy cleaner before and after each use.
