reusable ring sizer

Reusable ring sizer.

To measure your ring size put the ring sizer on the finger you want to measure, and pull it tight so it feels nice and snug on your finger. You can try it on a couple times to make sure it’s comfortable. Note down the number it shows – that’s the circumference of your finger in millimetres. Subtract 40 from the number and you get your polish ring size. : )
