Ass Ballz is a backdoor favorite. The heavy Baller is 100% Medical Grade, high end silicone with no filler. The seamless, matte surface is made of soft touch silicone. Each of the 4 insertion balls are 2” (5cm) with 2” (5cm) length of durable silicone between each. The Baller is extremely pliable and has a ringed handle for a secure grip and easy manipulation.
