This is an Italian Made Solid Sterling Silver Curb chain that is flattened a little more than the regular Cuban link chains which makes it wider but lighter and less costly than the regular Curb Link Chains. The Quality is Excellent, with a very nice, smooth, well polished finish and comes with a Lobster Claw Clasp for Great Security. The chain is Nickel Free. So it's Allergy Free, and Repairable and Re-Polishable.
