The ring sizer works like a belt, simply thread the end though the buckle and adjust it around your finger so that it fits. The number you will see through the magnifying lens is your size.
Please make sure you can also slip the ring sizer back over your knuckle comfortably.
Please check our size guide to make sure the ring will fit you
