Molded of durable polyethylene plastic, these boxes offer the convenience of light weight and handling ease. They are easy to clean as dried mortar can be loosened by tapping the outside of the box with a rubber mallet. Rotational molding process gives uniform wall thickness and makes these boxes extra strong to outlast other lower priced plastic boxes. Guaranteed, under normal use, against cracking or splitting. Length and width are approximate as measured at the inside top of the boxes.
