Each 2-Pack contains 2 size #21 Xact-Fit? rings. The incredibly popular PlayZone has proven our revolutionary Xact-Fit? 2.5mm (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. The sizing # references the ID in inches (#10 = 1.0` ID #11=1.1` ID etc) All 14 Xact-Fit? rings sizes are now available in single size 2-packs. 3 Ring Kits of M L XL and Mixed are also available. Don't know your size? We recommend you start with the Play Zone Kit which features 9 incrementally sized Xact-Fit? rings on a bright orange mini traffic cone. Each Xact-Fit ring is stamped with its size so no more guessing!
