Natural bleached bone nut block ready to be shaped and sanded and shaped to your custom specifications. This bone nut block measures approximately 52 mm (W) x 6 mm (D) x 10 mm (H) to accommodate nearly any sized nut. The nut is made from very dense cattle bone material which offers superior tone, sustain and easier customization. To install, sand the width first, followed by the depth and then the height (use your prior nut as a general guide as to the overall shape). A sample of 150-grit sandpaper will also be included.
