I am a big fan of homemade soaps and seek them out at every opportunity. Which is why I bought a few bars at the most recent Harvest Festival in Cooperstown.
I hadn't paid that much attention to the wrapper. The fish, however, should have provided a clue.
Anyhoo, I unwrapped the bar yesterday.

The front (click to embiggen).

The back.
Apparently, my soap is more than soap. It is a "Plan of Salvation." Which is a lot to ask from soap.
FWIW - the pumice in the pumice soap is extra-extra-extra rough. Bathing is like a punishment when using this soap. Feel free to write your own metaphor.
