These shallow containers with screw-top covers are made tin plated steel with threaded covers. Tins have no sharp edges, all edges are rounded and are seamlessly formed from .24mm metal. Price includes container and cover, which are shipped assembled. Dimensions are 13/16" depth and 2 7/16" dimension. Our tin cans do not have an internal plastic lining, therefore caustic substances may cause the steel to rust. Comes with 24 per pack.
