So far the best fingernails I played. However, it is recommended to have both large and medium because they can not fit perfectly each of your fingers. I added some bandage tape on the inside edge because they are pretty sharp. They still crush a bit my finger tips.. After one hour of playing I really feel the need to remove them off. I like much better the delrin ones, the tone is closer to natural finger tone. Give them a try.
They are fine but not perfect. They allow pretty fast rolls which is great. I like to play with them. Big minus is the price that is unacceptable. How can 3 plastic bits cost the price of a Boss cliptuner ?
