Provo Craft's Topaz Treasure Beadz are fine glass beads, silver lined for extra sparkle, and many are iridescent. Each color mix is made up of several different colors, shapes and sizes of beads. You can string them, glue them or tape them. When using with tape, first press on the Treasure Beadz, then fill in the spaces with Micro Beedz, glitter or other fine media in coordinating colors for fantastic results! Topaz Treasure Beadz come in a neat plastic stackable container.
