Size 8 MIYUKI® Japanese glass Unions™ seed beads with Czech glass finish. Approximately 3mm. Crystal Sliperit is a metallic iridescent purple/ pink/ orange/ copper color over a clear bead. Approximately 930 beads per 22-gram tube. The uniform size and shape of Miyuki seed beads make them an excellent choice for beadwork. The Czech glass finishes add spectacular color effects! We think these make excellent spacer beads for all types of strung designs. Depending on the angle, sometimes they look like a glass bead, and sometimes they look like a rounded metal heishi bead.
