Shigenobu Matsunaga, 2-sun extension, approximately 20kg. There is no damage to the outer or inner bamboo. The condition of the kanaita (handle plate) is also relatively good, I think. Please check the photos. The urazori (belly curve) is about 16cm. Please string it to your preferred degree after the product arrives. I regularly adjusted the bow's shape, and I felt it performed well even in recent use. I received it from a senior, but I'm not using it much, so I'm selling it. As it is a vintage used item, there is a risk of sudden breakage or adhesive separation. Please be aware of this before purchasing.
