These beads are plastic, white cube alphabet beads. The beads are 7mm in diameter with a 4mm hole. The holes are horizontal and run from left to right (side to side). The beads have letters or numbers on four sides. These beads have larger holes so they can be strung on hemp, leather cord, suede, lacing, lanyard, rattail and other thicker types of cords. They can also be used with thinner stringing material too such as gossamer stretch cord or flexible beading wire. You can purchase these beads as individual letter beads, as individual number beads, or in packages of mixed letter beads or mixed number beads. This size alphabet bead coordinates will with our 6x9mm Plastic Pony Beads.
