This is a set of two guitar saddles (bridge saddles) made of cow bone. These are unused items that have been stored. Made of natural cow bone material, these replacement parts are expected to improve the sound's attack and sustain. Recommended for acoustic guitar saddle replacement or as spare parts. Since they are in an unprocessed state, adjustments may be necessary to fit your guitar. Please refrain from purchasing if you are concerned about the fine condition due to storage.
