Thank you very much for viewing. Made by Master Shikou of Kishu. It's a 5.1. If I wrote honestly, it wouldn't sell, but when it came to me, the first and second joint mouths had soft wire cracks. The previous owner had lost the joint plugs, so the storage condition was poor, but I fixed the wire cracks myself. It's rock solid. It can be used properly. Tested (48cm) and raised, and it worked perfectly. How about it?
