The Gecko Grip is a simple yet powerful tool that tames both warped and slippery cutting boards. Sold in pairs, just place them under your board once and you"ll never cut without them again. The Gecko Grip works with wood, plastic and glass cutting boards gripping even the smoothest surfaces. Non-porous, food-safe silicone reduces the chance of cross contamination compared to the standard practice of using towels to stabilize your board.
