Bead rods in wood for the large checker board

Set of 18 including compartmentalized wooden box with lid.

Specially produced as a complement to the pearl rods.
When working with the Large Chessboard, which is made of wood, sometimes the bead rods roll.
This was brought to my attention by some students and then I decided to try to produce a bead material with square beads.
Now it's ready and I hope it will be a good addition to the otherwise indispensable bead material!
