For cool, subtle touches of color, try using these Hotfix XILION rose flatback in Pacific Opal from SWAROVSKI ELEMENTS. Each of these sparkling rhinestones features a faceted front surface in a soft blue shade sprinkled with an opalescent finish. Its smooth back is affixed with heat-activating glue so adhering to surfaces is easy! Note: The 2028 XILION rose flatbacks are being replaced with the 2038 XILION rose enhanced flatback, which has a mirrored back made from real silver for more intensity.
