This reusable ring sizer allows you to accurately measure your ring size so you can make sure you are purchasing the correct size for your new Katyb ring
Simply tighten the strap around your finger to see what size will fit you best. Tip - make sure you can slide this past your knuckle as this is generally the widest part of your finger
Katyb rings come in 4 sizes - N 1/2, Q, S and U. Set the ring sizer to each of these sizes to see which will fit best.
