Beads are fun but when the pros play, they get a Malesation Ball Plug - though courageous individuals are welcome to try. The plug gradually increases in diameter and it starts from an easy .75 inches and it builds up to a generous 1.4 inches at its widest. It is made from the best high grade silicone which is phthalate-free, soft, hygienic, non-porous, odorless, hypoallergenic, durable and easy to clean. Be brave and bury this bad boy down there today.
