These are tuning pegs for a Nakazao shamisen. I'm selling them as a set of 3 pairs. Ebony, Suroku Ebony, Mento Ebony with rosewood veneer, Mento The rosewood-veneered tuning pegs have "tochi" (figure) in the wood. The ebony Suroku also has a wood grain similar to "tochi" found in rosewood. All of them have ebony parts that touch the metal fittings (Fukurin) on the shamisen body side, so they hold well.
