"Friday the13th" Steel Ring

Size Guide

This is what you need: A piece of paper / Scissors / A tape measure or ruler / Pen or pencil

1 - Cut a thin (and long) strip of paper

2 - Wrap the paper around your ring finger just below the knuckle

3 - Mark where the two ends meet with your pen or pencil

4 - Measure how many millimeters from the mark you just made to the end of the paper you used. Match that measurement with the corresponding ring size on the chart

Or measure ring size with an existing ring. Use a ruler to determine the diameter of the ring and use the size chart to find your size
