Awesome quality, glass, nail art rhinestones, great selection of sizes with none being too large. High shine and sparkle, packaging is fantastic to keep each shape and size organised. There are x10 of the larger sized rhinestones, and many many many more of the smaller sizes. There seems to be a slight difference in colour between some of the round stones, although it is only slight and of no issue when combining with others. A great addition to any nail technician's tool box!
