Momohara Chiga, Chagi, Kwagi

This is believed to be a rare Momohara Chiga.
Among them, it is made using particularly valuable Chagi and Kwagi.
I believe the part that forms the core is Kwagi, and the sides are Chagi.
However, due to the artificial skin being tightly stretched on both sides and its age, the sides have started to crack.
It might be usable if you consult with a craftsman.
In any case, it is a valuable item.
