We have ordered extra materials for educational purposes, and will be offering the surplus. You may see these around, but please rest assured that these were purchased from a legitimate major wholesaler. This product (Yubikake - finger rest) is very easy to use, and we highly recommend it! We hope you will try it and experience the difference for yourselves♪ We also hope that you will help to preserve the tradition of the Japanese shamisen. ⚫︎Size: Medium ⚫︎Color: Beige ♦︎《Quality》 Wool: 50% Acrylic: 30% Polyester: 20% #Yubikake #Shamisen #Erhu #Mandolin #Sudare (blind/screen)
