Japanese households tend to have multiple cutting boards for use with different types of foods. That leads to clutter in the kitchen and higher water consumption. Given this situation, we developed a cutting board sheet that prevents cutting boards from getting dirty. It also prevents cutting boards from staining and odors. It's easy to use too. All you have to do is roll out the length you need and cut. The box comes with three meters of sheet and a slider to cut off as much as you want.
