I got my large chain for my Benten costume
from this online supplier: http://www.mrchain.com/collections/plastic-chain
They come in a variety of colors--silver looks nicely realistic in photos--and up to 5" in size per link. The one I bought for Benten's chest piece was the 3" chain, for comparison. If you need to hook the chain to something, just get a master link
in a matching size/color.
