Toho 2mm cube beads have a cube or diamond shaped hole, instead of a round one. This is an advantage due to the shape adding sparkle to the bead, due to the corners, and also the hole shape allows for more passes of thread. Toho Cube or Square beads are slightly larger than Miyuki Cube Beads.
We pack them in large 3" tubes, a tube holds appx. 13 grams. There are appx. 45-50 beads per gram so a tube holds about 600 beads.
