Material: Yaeyama Kuro-Yushigi (core) Type: Yonashiro type (Yunaa) Color: Light Sunchee Body: Double-sided genuine leather single-layer stretched Body Material: Chagi (Inumaki) Karankui: Same material sandwich, plum pattern Thank you very much for viewing this product. This is a Yunaa made with the core of Yaeyama Kuro-Yushigi, which is very valuable nowadays. The color was finished by Mr. H, who is No. 1 in Okinawa. This product is entirely handmade except for the strings and body wrapping, so it took a considerable amount of time. The type is Yunaa, but please check the photos and consider accordingly.
