Approximately 43cm, measured by an amateur. I tried to remove some dirt with a Canadian eagle, but it comes off, so I think it will be clean if you clean it before using it. It's quite old, so there are cracks, etc., so please judge for yourself from the photos. No claims accepted. Please read the profile before bidding. It came from an old house in Kamakurayama. It's from an old house over 100 years old, so it's quite old and has various issues like scratches, dirt, damage, rust, discoloration, dust, and mold, so please judge for yourself from the photos. No claims accepted. The era is also uncertain as it belonged to my grandparents, so I cannot specify it, so please judge for yourself from the photos. ‼️As it is a long-term storage item, please judge for yourself from the photos regarding scratches, dirt, stains, discoloration, dents, rust, damage, chips, mold, odors, and stickiness. If it is an unused item, it may require various adjustments and maintenance due to long-term storage, so if you are concerned, please purchase it from an authorized store. Returns are not accepted to prevent switching items.‼️ Please refrain from purchasing if you are a delicate person, a nervous person, or do not understand the meaning of used items.‼️ No returns or claims accepted. ‼️‼️Please be sure to read the profile before bidding‼️‼️‼️ Please use it after cleaning. I do not guarantee any problems during shipping. I am an amateur seller, so I will use air packing, etc., and will double, triple, or quadruple pack expensive items and precision instruments. Please refrain from purchasing if you expect more than this.
