The Swarovski 2088/I Rimmed Xirius Flatback Rhinestone provides a metallic rim coating around the edge of the 2088 Xirius Rhinestone for contrast to a few brilliant Swarovski crystal colors. The metallic coating offers an optical illusion of a metal rim - with all the beauty, but with no metal. The 2088/I is available in sizes SS16, SS20, SS34. These can be glued on just like other 2088 crystals using a Crystal Katana to pick them up and place them. They also come in a hotfix version for those who prefer to use that method.
