The Optimum Series Pure Skin Pump Sleeve Ass is a soft, smooth, and stretchy donut designed to fit over the base of a penis pump cylinder. Made from body-safe TPR in a pale peach colour, it is ultra stretchy, fitting most pump cylinders up to 3 inches in diameter. The sleeve has a snug opening designed to resemble an anus. The sleeve's tight opening and plush construction that contours to the body when pressed against it work in tandem to create both a comfortable cushion and a superior, air-tight seal.
