Beautiful walnut end grain chopping block finished with Howard's Mineral Oil and a generous rub of Howard's Cutting Board Conditioner. Preferred by chefs around the world, end grain fibers separate rather than sever when a knife passes along the surface. When conditioned properly, you can expect fantastic results for years to come. Sizes can vary and all are 1.75 inches in depth with four small rubber feet affixed to the bottom for a firm hold.
