This sale is for 12 vials of TruKay rhinestone birthstones. Each vial comes in its own envelope. The amount of stones in each vial varies. There are only 4 in the December vial, 5 in the August vial; but, the rest have more- some as high as 12. The stones are in great condition, I see no peeling. Most of the stones are the same size- 5mm, some are slightly larger. You are getting the lot.
