This is a sturdy rose gold filled rolo chain, great value! I really like rolo links, they hold together so well. The links are 1.4mm, and it has a 5mm rose gold filled spring clasp.  You will receive a 22 Inch chain I have this in 14, 15, 16, 17, 18, 20, 22, 24, 27, 30, 36 and 40 inch.. as well as in gold filled. I have a 1.2mm sterling silver rolo chain and a 1.1mm gold filled chain, as well as a 2.5mm rolo chain and a gold filled belcher chain that looks like rolo chain!
