Paulownia Cutting Board, Extra Large, New and Unused Size: 42cm x 24cm x 2cm This is the largest size available among those listed on Mercari. It's quite large, allowing for plenty of room for cooking. Compared to other wooden cutting boards, paulownia is overwhelmingly light, and because it drains water very quickly, it doesn't mold, allowing for hygienic use for a long time. I also have other cutting boards for sale! #mondo's Woodburning Cutting Boards If the thickness is thin, it may warp, but with 2cm, there's no need to worry about that. Vegetable and fish branding is stamped on it, so you can change the side you use depending on the food, making it hygienic.
