Very nice design. End cap (or cup) for 2 mm round leather. Spike presses into leather to secure -dab of glue too if you like. One side of the design stands out from the cup and there is a hole in the side of the cup - push the leather in and then squeeze the side down to punch into the leather to secure it. Kool, eh? Ring on the end to attach jumpring, clasp, etc. Lead, nickel and cadmium free.
Lead-free. Nickel-free. 6mm x 13mm By the pack of 2.
