These Two-Hole Tipp beads are the newest addition to the new Czech beads. The bead holes are large enough to allow for multiple passes of beading threads. These beads are made in the Czech Republic from pressed glass and have a very uniform size and shape. The corners are softly rounded and will not cut into your skin or thread. These beads have a 8mm diameter with two parallel holes each measuring 1mm in diameter. 20 beads per strand.
