I have ordered extra materials for educational purposes, and I am offering the surplus. You may see these around, but please rest assured that I purchased them from a legitimate major wholesaler. This product (finger rest) is very easy to use, and I highly recommend it! I would be happy if everyone could try it and experience the benefits. And, I hope that we can continue to preserve the tradition of the Japanese shamisen. ⚫︎Size: Medium ⚫︎Color: Yellow ♦︎《Quality》 Wool: 50% Acrylic: 30% Polyester: 20% #FingerSuri #FingerKake #FingerKake #Shamisen #Erhu #Mandolin #Suri (Blind)
