Great for sensitive ears! Safe for children's jewelry. Blends with skin, no need to match metal colors of other jewelry worn. Make unique earrings. Adhere tiny rhinestones, (either inside the cup or on the flat rim), pearls, zipper pull, charms, etc. Just about any embellishment up to maximum of 10mm. Take in to account the weight, and for best adhesion results-consider size ratio to the glueing surface. Nice for resale. They are practicallly invisible, secure, comfortable and cost effective.*GREAT VALUE*
