I was listening to the Larry Miller podcast, he was going on about saving soap slivers in the shower, somehow mushing them together to form a bar sufficient to bathe with. Apparently that is how they roll on the island of Milleronia.
Larry would be thrilled to have one of these Soap Banks. I found them in my dad’s old 1951 Jensen-Byrd wholesale supplier catalog. You just put your odd soap slivers inside, get it wet, and let the DuPont Cellulose sponge get nice and sudsy. That generation had endured the Great Depression and they were keen on saving money.
