Bring a stylish piece of flair to your designs with a Denim Blue Hotfix XILION rose flatback in SWAROVSKI ELEMENTS. Each of these sparkling rhinestones features a faceted front surface in a cool blue shade. 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.
