Use Czech seed beads for craft and jewelry applications that call for seed beads, charlotte beads, and/or microbeads. These charlotte beads have 1 to 5 facets each, making them a perfect way to add sparkle to your bead work. The production of Czech glass beads is a centuries-old industry in the heart of Bohemia. These glass seed beads are sold by hanks containing approx. 3,000 beads each. A hank is a grouping of several bead strands. This traditional packaging method verifies that all beads you receive do actually have a hole in them.
