I have extra supplies from a bulk order for educational materials. You may see these items around, but rest assured that I purchased them from a legitimate, major wholesaler. This product (Yubikake - finger rest) is very easy to use, and I highly recommend it! I hope you'll try it and experience the difference for yourselves. And I hope you'll join me in preserving the tradition of the Japanese shamisen. ⚫︎Size: Medium ⚫︎Color: Black ♦︎《Quality》 Wool: 50% Acrylic: 30% Polyester: 20% #Yubikake #Shamisen #Erhu #Mandolin #Sudare (blind/screen)
