Vintaj nickel-free brass rivet. Stack, layer, collage... Rivet pieces of metal, leather, plastic, and more together to create a multi-dimensional pendant! Simply punch or drill a 1.6mm hole into your pieces, and use a ball peen or chasing hammer to do the rest. It's fun, easy and addicting… you can rivet Vintaj charms, pendants, beads, flattened bead caps, hardware and findings to our Altered Blanks for a unique layered look.
