These Two-Hole triangle shaped 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.Bead Size: 6 mm x 6mm x 2mm thickHole size: 2 parallel holes each with a diameter of 1.25mmQuantity: 8 grams (about 70-75 beads)Material: pressed glass
