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 (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 yourselves. And I hope you'll join me in preserving the tradition of the Japanese shamisen. ⚫︎Size: Medium ⚫︎Color: Blue ♦︎《Quality》 Wool: 50% Acrylic: 30% Polyester: 20% #FingerSleeve #FingerRest #Shamisen #Erhu #Mandolin #Blind
