I bought this new about 5 years ago. I've only used it once or twice. It looks a little sooty, but I think it's usable without any problems. To prevent warping, I will ship it in a cardboard box. I may change the shipping method from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin, or from Raku-Raku Mercari Bin to Yu-Yu Mercari Bin. I will lower the price over time. Please refrain from negotiating. I have a pet (cat), but I do not smoke.
