Epicurean Cutting Surfaces® non-slip Gripper Surfaces are a perfect solution for smooth and damp preparation areas and for people who like more countertop grip during food prep. The corner placement of the silicone grippers elevates the surface off of your countertop while holding the surface in place and preventing it from slipping under the knife. As always, these surfaces are dishwasher safe. The silicone grippers are removable.
