100% BAMBOO Our bamboo cutting board is made of natural bamboo, keeping the natural bamboo texture. The surface is carefully polished and treated with food oil, making it smooth and no burrs, not easy to crack. It's wider, thicker, and sturdy so you won't feel it sliding on your countertop. Meet the demanding needs of chefs. REVERSIBLE & GENTLE ON KNIVES Since it's reversible, you can use either side or flip them over to change surfaces between raw and cooked ingredients. Smooth bamboo wood is also very gentle on knives, which is long-lasting and won't dull your knives.
