The Keepsake Collection of jewelry making supplies by TierraCast includes picture frame charms and connectors (links) for creating customized jewelry. Frame interiors range from 1.5mm to 1.8mm deep, giving you plenty of depth to add pictures, papers, fabric, thin layers of clay, and small 3-D embellishments. Use to feature family photos, doodles, craft paper, collage art, buttons, polymer clay designs, and more. Secure design elements with uv resin, epoxy resin, polymer clay, adhesives, or epoxy clay. NOTE: if you're using a glaze to seal images, do not use ink-jet pictures or the ink will bleed. These high-quality charm frames are made in the USA.
