Black acrylic "stones"

Over 90g of these assorted sized acrylic "stones". There must be a few 1000 in the bag. I know somebody will make good use of them. They are not flat backed - I think there must be a name for this shape. If they were diamonds I think they would be called "round brilliant" - which of course they are not, on either count. Not diamonds and not brilliant as black! Anyway this a a one off clearance pack. Do hope someone, perhaps working with polymer clay can find a use.
