Price listed is ten pre-set stones. These are approximately 4mm (probably 28ss) crystal Swarovski rhinestone set in brass four prong settings. The settings have slits on the side as though they were meant to be part of a chain. They could be used for stringing or sewing if you have a small enough needle. The stones are much prettier than they appear in the picture. Some of the settings may have the piece of the connector bar for making the chain stuck inside.
