We determined that we had to make rings that are only 0.1 inch apart in sizing to get rings that would fit perfectly. The new rings are call Xact Fit. Now we make 14 Xact Fit rings sizes where other manufacturers make only 3 to 5 sizes in this same range. We made them not too stretchy, so the rings are effective, but easier to get on and off than a metal ring. We know you will be surprised at how this sizing makes all the difference.
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 have favorite sizes you can order the perfect Xact Fit size individually in the future. Ring Number 17 1.7 inches in diameter, 5.3 inches circumference. Ring Number 18: 1.8 inches diameter, 5.7 circumference. Ring Number 19: 1.9 inches in diameter, 6 inches circumference.
