These butcher block countertops are made in the USA by John Boos & Co. Black Walnut is a top-selling North American hardwood, renowned for its dark and rich colors that add warmth to rooms. Blended-style butcher blocks are constructed using wood pieces of varying length to create the interior rails of the block, whereas the outermost rails feature wood strips that run the full length of the block. The result is a pleasing array of creams and medium-to-dark browns. These particular counter tops are 1-1/2 inches thick, 32 inches wide, 145 inches long, and finished with food-safe natural oil, making them safe for cutting upon. WALNUT BLENDED KCT 145X32X1-1/2 OIL
