2028 XILION rose flatbacks are wonderful for providing a touch of sparkle to your designs. Their shape makes them an easy choice for a variety of projects. When using flatbacks you should never use a glue gun or super glue, as this will damage the foil backing. Note: The 2028 XILION rose flatbacks are being replaced with the 2058 XILION rose enhanced flatback, which has an improved table size for added color intensity and brilliance.
