Handmade and each unique. These turtle pendants are made one at a time and are all different in there own ways. Being handmade there may be some imperfections. It is possible to get one with an indent in the back (you can't see it when wearing). I leave some bubbles in the resin because 1) you can't get them all and 2) the ocean has bubbles. I also feel that it adds to the charm. Each pendant has been crafted with UV resin, real shells, resin starfish and sand from the Arizona desert. Each pendant is strung on a simple wax coated nylon strap with a metal clasp which measures 18 inches. Please pick which one you would like and you will receive that EXACT pendant. Thank you for looking and check back as I will be adding more. The turtle pendant is 2.5 inches long and 2 inches wide, the square pendant is 2 inches long and 1.5 inches wide. The video shows other styles that I can make.
