1. Bottom rolled edge design: The bottom rolled edge design makes it difficult for food to spill, can be hung or stored upright, save space, and has a rubber non-slip pad on the bottom 2. BPA Free: The cutting board set is made of PP material, which is thicker and heavier than ordinary cutting boards. It will not hurt the board or knife when cutting vegetables, nor will it split or crack. And this cutting board is non-porous and water cannot penetrate easily, so these boards are dishwasher safe. BPA-free cutting boards are getting better and better. 3. The set contains three sizes of cutting boards: large (10 inches by 13.6 inches), medium (8.6 inches by 11.6 inches), and small (7.8 inches by 9.9 inches). Tough enough to withstand heavy-duty chopping, slicing, dicing, and sharp knives, our surface will not retain stains or odors in long-term use. This 3-piece multi-purpose cutting board set is designed to make meal preparation easier and cleaner, allowing you to protect your counters while preparing meals.
