I purchased these nails for my Tribal Fusion bellydance class, and they are great for your first set of Thai fingerclaws. The brass is lightweight and very flexible, so you can adjust them for your fingers. The only problem that I ran into is that they are made for very small fingers, so some of my students with arthritis have a difficult time adjusting them to fit around their knuckles. But they still work. The prices were unbeatable, the shipping speedy, and the customer service sincere. Great doing business with Red Berry.
