This adjustable ball stretching cuff has two D-rings at the bottom, which lets you attach additional weights for even more resistance. As the balls retract during sexual stimulation, the resistance creates a pulling sensation which can add an extra dimension of ecstasy as you play. Whether worn as a traditional ball cuff or used as a weighted ball stretcher, this fabulous leather item is the perfect scrotal accessory. Material: Leather, metal. Color: Black. Note: Ball weights sold separately
