The lovely scalloped shape adds interest to these sturdy wood bowls. The individual bowls are 6" across; the large salad serving bowl measures 12". They're made of Acacia, a dense, naturally resinous hardwood that will not absorb stains or odors. The bowls are hand turned from one solid piece of Acacia hardwood, making each piece a unique, sculptured work of art. Hand wash with hot water and a little dish soap; dry thoroughly before storing.
