The cutting board is foldable, magnetically detachable and doubles as the enclosure for your Prepdeck unit. Our durable cutting board is made of BPA-free, antibacterial, food-safe polypropylene and is intentionally designed to score with use; keeping your knife sharper, for longer. The magnetic enclosure makes it easy to detach and clean or swap out if, for example, you are worried about contamination when switching between cutting meat and veggies. We recommend washing the cutting board by hand. Our Prepdeck+ comes with 2 cutting boards.
