Each 2-Pack contains 2 size #23 Xact-Fit rings. The incredibly popular PlayZone has proven our revolutionary Xact-Fit 0.1 incremental cock ring sizing system is the most precise on the market. Super strong, but soft to the touch, Xact-Fit rings stretch just enough to get on and off, but otherwise should provide a very comfortable (no pulled pubes!) and effective fit. Each Xact-Fit ring is stamped with its size so no more guessing! Stack the rings for additional fun.
