I have extra stock of teaching materials, so I'm offering the surplus. You may see these around, but rest assured, I purchased them from a legitimate major wholesaler. This product (finger rest for shamisen) is very easy to use, and I highly recommend it! I'd be happy if everyone could try it and experience the difference. And I hope you will continue to support the tradition of the shamisen, a Japanese tradition. ⚫︎Size: Medium ⚫︎Color: Black ♦︎《Quality》 Wool: 50% Acrylic: 30% Polyester: 20%
