I knitted this based on the advice of my shamisen player mother. It's designed to be less likely to stretch vertically and to stay in place during performances, with a wider surface area. Length: Approximately 8.5cm Width: Approximately 3cm Between thumb and index finger: Approximately 4cm Color: Yellow Material: 78% cotton, 20% polyester, 2% rayon Please purchase only if you understand that this is handmade.
