Made by us. Brass Please refer to the scale in the image for the size. The background grid is also 1cm x 1cm. We modified a number bolt, which is also on sale, to make a pendant. The jump ring is not soldered, so it can be used as a pendant, key holder, or other items. The chain in the image is sold separately. We also have the same design in German silver.
