Antique D-Lite Dishwashing Detergent Box Soap Advertising For Sale

Antique D-Lite Dishwashing Detergent box. The box is sealed, but I\'m not sure there\'s soap in the box. It weighs appropriate to the 1 1/2 lbs listed on the box, but the box is hard, like there\'s something stiff inside. And when you shake it, there\'s no indication anything is inside. I received it this way, so I can\'t say it\'s a sealed, unopened box. Measures 9\" x 7\" x 2\".
