These two-hole dagger beads are part of the Czechmates 2 Hole beading system, with the holes perfectly aligning with those of the other two hole beads manufactured by Starman (including the two-hole tile beads). The bead holes are large and 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. See for yourself. These beads measure 16mm X 5mm X 3mm and have two parallel holes each measuring 1.25mm in diameter.
