For picking, sorting, transferring beads. The triangular shape and straight edges allow the bowls to be used as a hand shovel. So you can sweep up lost beads right away. Sort your beads into different bowls at work. The beads are easy to see on the bright aluminium. When you're done and want to pack away your beads, you can easily fill them into small bags, tubes or compartments from the corners of the bowls. The weight of the bowls is so low that we also use them as trays for weighing the beads. The bowls are stackable so they are easy to pack for on the go. DIMENSIONS The sides are 4 inches long, the edges are 0.25 inches in height.
