Why don’t soap companies put bars of soap in water-proof containers? It’s not like they don’t know that soap is going to be used in an environment where their product will be exposed to water. The whole idea of soap is that it’ll be used near water.

It seems logical that soap would come in a waterproof container. I mean, shampoo does. Conditioner does. Toothpaste comes in a waterproof container! So do most toothbrushes, for that matter. How much extra expense would it be for a soap company to package each bar of soap in a thin plastic box instead of the turn-to-mush-instantly-on-contact-with-water cardboard boxes that soap companies like to use?
