I received this as a giveaway at POLUS, but I'm selling it because I don't use it. One of the features of this product is that the lid can also be used as a cutting board. Please follow the points below and try using it for light cooking during outdoor activities, etc. ・When using it, choose a flat and stable place. ・Since it's a simple cutting board, it's not suitable for hard ingredients, slippery ingredients, or large ingredients. ・Be careful as applying the knife too strongly may cause scratches or tears. ・Do not place hot pots or dishes on the lid.
