This kit has 12 sizes of round pointed back clear crystals. So far I have used them to turn some rainbow studs in a prong setting into clear crystal, which worked better for a project. I really like the container which seals each square compartment into a separate chamber.
I bought 2 of these boxes and probably should get some more as the rhinestones are beautiful and it is always nice to have lots of sizes at hand when you have to replace rhinestones in costume jewelry. Very happy with my purchase!
