Thank you for viewing. This is a Soya Kyugu Ten's "Tsuka-banare" (grip release) for yumi archery. I used it for about six months, but I'm selling it because I no longer use it. It's a semi-custom order, size M, which is about size 6 in Kato Kyugu's sizing. I think it's easy to apply "giri-ko" (rosin powder) and easy to draw. If you want to try a "yotsu" (four-finger grip), please consider buying it. Feel free to ask any questions you may have.
