Made from anodized aluminum and EPDM or neoprene rubber (both nonlatex polymers).  No clasp needed.

Everyday Jewelry

These are just comfy.  You can wear them everywhere, and they keep their good looks.  Also super light weight, and no clasp. With a huge variety of colors to choose from, you can hardly go wrong.

I'm always looking for new weaves that can be done stretchy, so check back often for updates.
