Glue on bails can be used on any flat surface stone, pendant or other object, use small for earrings and the large for pendants. Use BeadFix adhesive, BeadFix Gel, E6000, or BeadFix Adhesive Squares on these custom findings. Larger bail has ample surface area for adhesion of large cabochon cut stones or flat-back Austrian Crystals. Top of bail can be used showing or concealed (behind larger items). Simply affix with bail in the flat position on the back of the stone. Groves in the metal help with adhesion and offer design on the portion that is exposed.
