[Source] Silver chain and Leather belt straps

Hi Everyone!

Does anyone have a really good source for sterling chain if you are
buying in bulk quantities (50 chains or more of each type). I’ve
checked Rio, etc. but know that there has to be better deals (for
chains already finished, not spools). Specifically I’m looking for
18" venetian box, rolo, figure eight and diamond cut bead chain.

Also, I need a source (preferably in LA Garment district?) for
distressed leather belts with snaps to attach buckles (that I make).

Thank you! Suzanne
