For the guitar builders, repair techs, and serious DIYers out there – this 10-pack of blank bone nuts is essential workshop stock. Each piece is a fresh, uncut blank made from real bone (a classic material loved for its tone and durability), measuring approximately 55mm long, 6mm thick, and 10mm tall (that's about 2-1/8\ x 1/4\ x 7/16\). They're brand new and perfect for crafting a custom nut for almost any type of guitar – acoustic, electric, bass, classical, travel guitars, even ukuleles or cigar box guitars. Because they're blank, you get to slot and shape them exactly to your instrument's string spacing and neck width, which is way better than a pre-slotted plastic nut. The brand is RingRing, MPN 19851106, made in China. Having a few of these on hand means you can fix a broken nut or upgrade a cheap plastic one on any project guitar. For the price of a couple of fancy coffees, you get enough material for multiple repairs or builds. A must-have for anyone who works on stringed instruments.
