Toho 11/0 Triangle beads have a triangle 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.
We pack them in large 6" tubes, a tube holds appx. 25 grams. There are appx. 82 beads per gram so a tube hold approx. 2050 beads
