The Swarovski 2078 hot fix flat back rhinestone is the enhanced cut XIRIUS Rose, improving on the already amazing Swarovski 2038 XILION Rose Flat Back Rhinestone. This revolutionary crystal is named after Sirius, the brightest star in the galaxy. Like all modern Swarovski crystals, the 2078 Xirius hotfix flat back crystals have a flat reverse side that has been pre-coated with a heat-sensitive glue. They can be easily applied to a large range of textiles and other materials. It is made with the lead-free, superior Advanced Crystal formula, and is manufactured according to the company's strict socially and environmentally responsible standards. Shown in Crystal Ivory Cream and in size SS34. Because of the unique coloration of this item it has a transparent hotfix adhesive (HFT). This beautiful Lacquer Pro color from Swarovski is created not by tinting the crystal but instead by using a unique colored foiled which radiates through the clear crystal. This gives a different look compared to traditionally colored crystals.
