These are gorgeous vintage natural material! I have been hunting and hunting and finding nothing. Finally found an old couple who had this stock and very little of it. However they had just come from a show and saw what dealers were getting or it so they didn't let it go without a fight and without a price. The lot is for 20 beads that measure 3 mm and they are fully drilled. I just put up the third pic to show various color SB I have. The smallest are the ones in this auciton. The largest are on the left at 6mm and the most vivid blue are on the right and are 5mm.  Please email for info or to set up BIN.  Please visit our other aucitons for lots of jewelry making goods. thanks
