This is a handy and accurate ring sizer that you can use and reuse anytime. It is very easy to use and a must-have tool for anyone who wants to order rings. 
 
All you need to do is:
Push the end of the ring sizer through the buckle and slide it onto your finger. Make sure it can slide off over your knuckle easily.
Read the ring size by the arrow that points to the scale. It measures UK ring sizes up to Z.
 
It is very important that you order the right size for your ring. The difference between sizes is only 1mm, but this can make a big difference in how comfortable your ring feels. If your ring is too loose or too tight, it can cause problems.
All our rings are custom-made to fit your finger. We recommend that you use this professional ring sizer before you order.
