Nero Violin buttons are engineered for durability, beauty, and comfort. The flat model with concentric rings is an attractive addition to any instrument, and the nearly flat profile is extremely comfortable for all players. The stability of the Nero material will not distort over time due to humidity, temperature, or abrasive body oils or sweat. The shaft it not turnable, so the hole has to be reamed at an appropriate dimension.

Sold in lots of ten.
