The black rings in this bracelet are stretchy! They are made of EPDM, a fade resistant, safe kind of rubber. The silver rings are bright aluminum, which does not rust or tarnish and is very lightweight. Stretchy rings means there is no need for a clasp! Just slide it over your hand, and you're good to go. I can make these in lots of other colors as well. Just contact me if you'd like a bracelet of different colors and I'll be happy to make one for you! ♦ Material: Bright aluminum and EPDM rubber ♦ Color: silver and black ♦ Length: About 7 inches, stretchy (fits a small to average sized lady) Size adjustments can be made for no extra charge. ♦ Weave: Half Persian 3 in 1 (hence the name)
