Made from black walnut  finished with natural food grade oil/wax   Size about 4 in long  2 1/2 in deep 1 1/2 by 1 1/2 wide    Is black walnut wood good for anything? Black walnut timber is very highly prized for its straight, dark, heavy, strong, fine-grained heartwood, which is used to make fine furniture, valuable gunstocks, flooring, oars, and coffins. Because the species is now relatively rare in the wild, the timber is currently used for veneer as well.
