they are from a soda plant -------- I do not know if there is a different between the craft type of bottle caps you buy at the craft stores or not????? They look like they'd work good for neglaces, magnets to me. But I haven't done bottle cap crafts myself yet - well I made 1 magnet :) put a bunch of glitter inside a bottle cap and turned it into a glitter eyeball it was cool : )
OK, Thanks I want them to bottle our root beer with so now I am bidding! :) I am not sure the ones for crafting would work but I would hate to find out the hard way!
