These are both from an Italian company known for its quality design and use of bronze (and other precious metals). The hollow one has a working hinge and it snaps closed. It has a few minor scuff or scratch marks. The thinner one is solid bronze and really has a MCM look to it. I put them together because they are both from MILOR and are both made of bronze. I guess I always thought that bronze was more of yellow gold color, but these are both a rosey gold. I almost didn't belive thaty were bronze at first. This rosegold color was so unexpected. It’s more peachy rose than it photographed. It's a fabulous pair of bracelets. The hollow one weighs 1.23 oz, and the solid one weighs 1.66 oz.
