FLOW is the world's first perforated cutting board and the last one you'll ever buy. Holes in the cutting surface allow juices to flow into the tray beneath, which can be used in recipes or disposed of. Interchangeable boards help prevent cross contamination. Non skid feet keep FLOW anchored to your countertop. Dishwasher safe and BPA free. What more could you want in a cutting board? Don't believe us? See for yourself!
