These are sold in dozen packs, if you buy a quantity of 12 you actually get 144pcs. Do you need a simple snap bail and do not know which one to get... I would recommend these. These are brass with an antique bronze finish. I like the size on these as they are large enough to accommodate most chain, neck rings, or chords, but they taper down to a narrow base allowing you to clip through a very small pendant ring.
