I'm offering the surplus from a bulk order of teaching materials. You may see these around, but rest assured, I purchased them from a reputable, major wholesaler. This product (Yubikake - finger rest) is very easy to use, and I highly recommend it! I'd be delighted if you could try it and experience the benefits for yourselves. And I hope that we can continue to preserve the tradition of the Japanese shamisen. ⚫︎Size: Medium ⚫︎Color: White ♦︎《Quality》 Wool: 50% Acrylic: 30% Polyester: 20% #Yubikake #Shamisen #Erhu #Mandolin #Sudare (blind/screen)
