This is a new, unused nut. The stated size is 38 x 3.5 x 6.0 (mm), so please be sure to check the size before purchasing. The nut width is likely close to that of a Jazz Bass. I cannot determine if it is cow bone, but it is a bone nut, so it is recommended for those looking for bone material. This item will be sold with shipping included, so please purchase it as soon as possible. No discounts will be offered. If you purchase two items (you can also combine with a P-bass nut), the price for two will be 1500 yen, so please comment before purchasing. Other musical instruments are also available at great prices. These are pre-slotted nuts, but whether the slots are suitable will depend on each individual instrument. ↓Musical instruments for sale here #ApacheMusicalInstruments
