Premium Food-grade MaterialsOur cutting board is made of high-quality food-grade PP. It's BPA-free and dishwasher safe. Premium Cutting Board Rack: The space-saving cutting board rack makes it more convenient for you to store cutting boards, and makes your kitchen countertop look tidier. After cleaning, use the cutting board rack to drain. The rack separates cutting boards from each other, which allows air to circulate naturally and discharge moisture, and prevents the growth of harmful substances due to close contact and excessive humidity. This provides a more convenient and safe storage method. Dishwasher Safe and Easy to Clean: Food residues and juices cannot adhere to the surface of the cutting board because the surface of the cutting board is compact and non-porous, which makes the cutting board easy to clean and dishwasher safe. Healthy Food Classification Design: Experts suggest that food should be classified and cut when it is prepared for cooking to stop harmful substances from crossing between raw and cooked food. Concise and clear food markings and gradient colors design can help you sort food more easily, and colorful design will decorate your kitchen.
