This bowl is made from a solid piece of Walnut wood. It's a raw bowl, which means it has been treated with mineral oil and wax and has no other finish on it. It has been professionally dried with no cracks or flaws. It's a beautiful representation of American craftsmanship. The piece measures 12" across and stands 3.5" tall and has a flat bottom unlike other raw bowls on the market today. It's the perfect size for the family salad! Don't forget to order salad servers!
