Toho 2mm round, flat, glass Demi-Round beads are about half the height of an 11/0 seed bead. Approximate measurements are 2mm diameter, 1mm high, with a 1mm hole. Demi-Round spacer beads are sold in 5g bags, unless otherwise noted, which contain approximately 925 beads. Use them in stacks or singly to separate other small seed beads. Please note that Toho Demi-Rounds are slightly smaller in diameter than Miyuki's Spacer Beads.
