The picasso covering on these jet fire-polished Czech glass beads creates a unique speckled effect. Try these beads in place of plain black glass when you want extra texture and interest in your designs. Their 4mm size works well for spacers or for more delicate designs. These beads come in a 100-piece pack. Glass making in the Czech Republic is an age old cottage industry. Since these beads are still made in small quantities by hand, there may be slight color variation from one batch to the next.
