Made in the Czech Republic, the facets of these fire polish beads are first cut by machine. Then the surface is polished as they are fed through a red-hot oven. The heat from the oven softens the glass surface, removing any marks left over in the cutting process. Most of our inventory is temporarily strung. Please note that small imperfections will occur as part of the manufacturing process and size, shape and color may vary slightly from lot to lot.
