Thank you for viewing. This is a Soya Kyugu store's "Tsuka-banare" (grip release) for yumi archery, a type of four-finger release. 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. If you'd like to try a four-finger release, please consider buying it. Feel free to ask any questions you may have.
