This is a Hinoki (Japanese cypress) cutting board purchased from "Kitou, Kurashi no Dougu-ten" (Nordic, Tools for Living). (This is a set of two, medium and small, for sale.) I stored it in a dark place for a year after purchase, but I'm selling it because I don't seem to have a chance to use it for a while. The scent of Hinoki remains to some extent. The paper with usage and care instructions was included, but I have disposed of it, so it will not be included. I will include the online site's content below. Please understand. Please refrain from purchasing if you are nervous about home storage. [Product Name] Aomori Hinoki Round Cutting Board / Medium [Price (tax included)] 5,720 yen Size mm (approx.) Diameter: 300, Thickness: 20 [Product Name] Aomori Hinoki Round Cutting Board / Small [Price (tax included)] 5,225 yen Size mm (approx.) Diameter: 25.4, Thickness: 20 ●Care Instructions ・Washing and drying with a dishwasher or dish dryer will cause warping and cracking. ・Do not leave the cutting board in water for a long time. If the wood absorbs too much water, the wood will age faster, causing blackening and cracking. ・Do not use bleach, as it will damage the wood and cause the surface to become fuzzy. ・When using, place a tightly wrung wet cloth under the cutting board to stabilize it. ・Since the cutting board is about 2cm thick, use a stand that is 2cm or more wide.
