This bracelet is made from long drying resin that has cured and then been sanded and polished to a high shine. It measure 1 1/2 inches wide and 8 inches in length. My wrist measures 6 inches and the picture was taken on me. If your wrist is smaller it would be a loose fit and larger wrists have room. The opening in the back is 1 1/2 inches wide. The original post is in what I call peacock color which is blue, purple and teal mixture. I will take color request and if you look under other resin products you will see the sky is the limit. I have other resin bracelets in other styles so please check them out.
