Imagine if a finger ring only came in three sizes equivalent to the circumference of a dime and a quarter and a dollar coin - how would they fit? Well until now, most cock rings have been sized even farther apart than this! No wonder finding a good fitting cock ring can be difficult.

Perfect Fit has developed a cock ring sizing system designed to fit you without too much pull, but with enough restriction to be truly effective. They determined that they had to make rings that are only 0.1" (2.5mm) apart in sizing to get rings that would fit perfectly. These new rings are called "Xact-Fit."

These rings are not too stretchy, so the rings are effective, but easier to get on and off than a metal ring. The Play Zone kit contains the nine most commonly used Xact-Fit sizes for shaft rings, ball rings, and cock & ball rings. Made of a plush soft touch silicone, the Xact-Fit ring is premium quality and incredibly strong. Each Xact-Fit ring is stamped with its size so no more guessing! Stack the rings for additional fun. If you if have favorite sizes, then you can order those specific sizes in the future. The Play Zone comes with a storage cone designed specifically to hold the Xact-Fit rings perfectly.

The Play Zone comes with PF Size #11-#19.
