Thank you for viewing. This is a working Zoid, the "Gairyuki" (Gairyu-ki). The battery box is clean and it works, but there is a slight catch in the gears. There is dust and dirt. There is no instruction manual, and I don't know if all the parts are present. Please check the photos and understand before purchasing. To prevent damage, I will disassemble it to some extent for packaging. Thank you.
