"A clever way to organize beads while you work. Pick up, sort, and pour beads/stones. The triangle shape & angled edges allow you use these trays as clever little bead/stone scoops to chase down errant beads/stones. Sort your beads into different trays while you're working. When you're ready to put your beads away, pour them directly from any corner into small bags, tubes, or compartments. So lightweight we use them as tray on bead weighing scales. These trays nest, so they are easy to pack along for beading on the go. Bright white lets you see your beads clearly. Measurements: 3-1/4 inch x 1/4 inch H."
