Press the lever to open. This clasp is designed for loomwork and bead weaving projects. The end that attaches to the work is a open tube with a slot, and little foldable flaps to cover the ends. The inside diameter of the tube is 2.8 mm, and has a bit of wiggle room. It will easily take up to size 8/0 seedbeads. Slide the end row of your piece into the tube, and fold down the flaps to hold in place.
Made in Germany. 10mm x 18mm By the each.
