Aside from the obvious, it fills the bill for attachment material, for bridging from one element to another, for finishing around the back of the neck.
Many of the chains we offer are overlayed instead of plated. The overlay process lays down about three times as much metal as the plating process, making the finished product stand out.
Generally chain is sold by the foot, so plan accordingly.
And sorry, but all chain cut to order is not returnable.
