Nickel silver 6mm diameter 8cm per side It's small, but I think I've managed to create a good sound. The resonance is good, but there's no volume. It's very small, so that's to be expected. It gives the impression that it can be played at the instrument's volume without consciously trying to suppress the volume, like in a small ensemble with pp to p dynamics. The fact that you can hit it without it buzzing might be a merit.
