These sparkling XILION rose flatbacks from SWAROSVKI ELEMENTS come in an attractive yellow-green hue called Olivine. Use them to provide sparkle to vintage-style designs or mixed with other colors on anything from fabric to greeting cards. Please note that when using flatbacks, you should never use a glue gun or super glue (cyanoacrylate) as these glues will damage the foil backing on the rhinestones. Also be aware that while flatbacks are terrific for adding sparkle to clothing they should never be dry cleaned.
