Rectangular shaped tins are steel containers with slip on covers. Tins have no sharp edges, all edges are rounded. Tins have seams across the depth dimension. All cans are made from .24mm metal. Price includes container and cover, which are shipped assembled. Outside dimensions are 4 3/4′ length X 3 3/8′ width X 1 1/2′ depth. Actual outside dimension measures with an additional 3/16′ or 1/4′ more. Our tin cans are made of 100% steel and do not have an internal plastic lining, therefore caustic substances may cause the steel to rust. Comes with 24 per pack.
