We have ordered extra materials for educational purposes, and will be offering the surplus. You may see these around, but they were purchased from a legitimate major wholesaler, so please use them with confidence. This product (finger rest) is very easy to use, so we recommend it! We would be happy if everyone could try it and experience it for themselves♪ And, we hope that you will continue to protect the tradition of the Japanese shamisen. ⚫︎Size: Medium ⚫︎Color: Red ♦︎《Quality》 Wool: 50% Acrylic: 30% Polyester: 20% #FingerSuri #FingerKake #FingerKake #Shamisen #Erhu #Mandolin #Suri
