FlipRings are medical grade silicone, hypo-allergenic, ultra-comfortable, waterproof, and won't rub off on your skin or clothes. Weight: Incredibly light. Width: 6mm. Thickness: 2mm. Flip Rings are one size. They are designed to fit snug but will stretch and conform to your finger. Technically speaking they are a size 7 (17.2mm diameter) which is the average women's ring size in the U.S. Not sure what your ring size is - it doesn't matter. Wear them on any finger, thumb or even toes. It's all good.
