Interesting item. A hoop with a post and a hole. Use as a link or floating ring or what ever you come up with. Line the post up into the hole, and squeeze shut with pliers. Squeeze on the end of the post as you do this, and it will thicken the post and flatten the end, making the joint permanent (sort of like rivet). Very low fuss. Not intended to be reopened. Lead, nickel and cadmium free.

Lead-free. Nickel-free. Made in Israel. 6mm x 9mm By the each.
