Up for auction are 40 pieces of piano key ivory.  I aquired these at an estate sale of a retired piano repairman.  They were in a box marked "old ivories"  They are used and in different shades.  They are sold as is..... I think they would be fine for your craft purposes.  Please email any question.  I accept cashiers checks or money orders, no paypal or international bids.  Thanks for looking and please check out my other auctions.
