Yakumo strings with string loop adjustment function. 【Important Notes】 The thin side of the string loop (see the second image) is not doubled, so the original yarn is more likely to be exposed. However, it is designed so that the exposed part does not touch the corners of the yugake (bow grip), so it will not lead to breakage and can be used as is. Recommended bow weight: ~20kg String dimensions are for [Ren-shin, Jiki-shin, Koku-shin] bows. Use the naka-jikake (center serving) by wrapping hemp or synthetic fiber over the base. Keep away from fire, sharp objects, and maten-so (a type of moth). This product is a loop-type string. Adjust the height by twisting the string. Compared to other makers, this product is relatively low-priced because it is only pre-made and has not undergone maintenance. Basically, no returns or exchanges are accepted.
