These thin Gunmetal Black plated bead caps are stamped in a six petal flower shape with open spaces within and between the petals. Caps can be easily flattened so they can used with a range of bead sizes. We show 6mm beads in the picture, but they can easily be used with sizes at least up to 10mm and perhaps larger. Caps are about 7x4mm, 1mm hole. Sold in packages of 36 bead caps.
