These are solid brass ball chains, and are lacquered and polished.
There are hundreds of uses for brass chains and fasteners. Anchor sleeves are used to tether chains (e.g., on ballpoint pens in banks), loop links can be used with chains to make key chains or non-slip loops of any size, and end anchors let you make lid chains for chests and boxes. The anchor sleeves, loop links and end anchors are available separately.
#3 and #10 ball chains sold in 10' or 50' lengths.
