This Multisizer measures in whole and half US ring sizes from 1 to 17.

It works like a belt. Simply push the end through the buckle to form a ring shape. Slip onto your finger adjusting for a comfortable fit. Make sure you're able to slip the plastic ring sizing tool back over your knuckle. When the best fit is achieved, take note of the measurement marked on your Multisizer.

Ensure that you check your ring size more than once. A warmer weather will cause your fingers to swell, and a cold weather will cause them to shrink. Check your size on a cold and warm day.

Along with the ring sizer, you will receive a coupon code for a $5 discount on any Marmalade ring.
