Review on KIWEN Ring Sizer Set: Metal Finger Size Gauge Measure Tool for Accurate Jewelry Sizing - Rings Size 0-13 with Half Sizes (27 Pieces) by Morgan Gilmore

Sizing information is easy to read; Each number is legible, clearly engraved in approximately 12 point font. All gauges are attached with a strong metal loop. Reviews tagged "Most Helpful" state that this meter is inaccurate; However, there are far more positive verified reviews than theirs, so I gave it a try. Result: I bought 2 rings as indicated in the KIWEN Ring Sizer. The rings arrived but they didn't fit both of us - they were too small. We had to increase the size by 1/2! It turns out other reviewers had the same experience. This set is 0.5 small. If you order this size, find your size with the KIWEN ring sizing kit THEN increase by 0.5. I would also look for an alternative size that fits quarter sizes. But if the ring you buy has a pitch of 0.5, then that's fine too. Remember to increase the size in half.
