This listing is for a sealed packet of 128 black and white letter beads. The beads are white and the letters are black. The beads are plastic and the white part has a soft shine. The square beads have the same letter embossed in four of their six sides (two sides are for the hole, which measures 3mm). The square beads measure 5mm across.
The loose beads in the first photo are not the same as those in the bag; they are just for the photo. The beads in the bag are random, so I cannot predict which letters are included. But they are fun to work with and can even be used in a macrame bracelet. The packet advises use in children older than three years.
