1. Choose a ring that is comfortable for you to wear;
2. Then place it on one of the different circles present in the ring sizer;
3. Test each of the circles by placing your ring on the screen, until you identify the inner diameter that coincides with your ring. The diameter of the latter corresponds precisely to the interior diameter of one of the circles? Well done ! This means that you have identified the finger size that suits you best.
4. Add the corresponding nummer in the note of your ring order.
