Ring Size Guide
Step 1:
Prepare a slip of paper. Draw then cut out a T-shape with a small rectangular hole. Make sure the end could pass through the hole.
Step 2:
Thread the end through the hole. Put and fasten it just right on the finger. Fold in the opposite direction.
Step 3:
Measure from the length of the rectangular hole to the folded line. Check out your finger size according to the mm measured.
