This is a diagonally cut cutting board. It can also be displayed stylishly as interior decor. I received this as a gift, so I don't know the type of wood or oil used. ■ Size Length: Approximately 37.5cm Width: Approximately 12cm Thickness: Approximately 2cm Because it is natural wood, warping and twisting may occur. Do not put it in the dishwasher or dryer.
