These SS20 (4.8mm) Swarovski 2088 Flatback Crystals in the color Indian Siam 327 (red) are great for adding to your dance costumes, pageant costumes, nails, make up, clothing and accessories to help them sparkle and shine. The brilliant facets on these Xirius Rose crystals shine beautifully when moved in the light. These crystals are made with a silver foil backing that helps create a perfect sparkling finish. They can be applied to most surfaces using glue or with metal settings and the Brisk set rhinestone setter. We recommend using Gemtac for fabrics and E6000 for other surfaces. The crystals come in specially designed jars for convenient use and storage. M&J Trimming is an Authorized Swarovski Reseller and has been selling Swarovski crystals for over 30 years.
