The cutting board is a 12 inch square and is white food grade polypropylene. It has stainless steel spikes, half inch high corner guards and four suction cups. The spikes are there to keep the food in place while you are cutting and peeling. The corner guards are to help make it so while you are spreading things, like butter on bread, the bread doesn't slide all around. The suction cups are to anchor the board while it is in use.
