Enhance your designs with these XILION Rose White Opal flatbacks from SWAROVSKI ELEMENTS. These little beauties have a touch of warmth to their tone that complements their sparkling appearance. Glue-on flatbacks, also known as rhinestones, are a great way to jazz up your creations. Please note that when using flatbacks, you should never use a glue gun or super glue as they will damage the foil backing on the rhinestones.
