This is a soap bar unlike any other. Made in France, it is a porous, pumice-like terra cotta (baked clay) impregnated with a long-lasting soap. It is gentle on the skin but vigorously removes dirt and stains. Because the soap has been centrifuged deeply into the terra cotta, it will typically last a year, even with daily use, as long as it isn't left sitting in water for long periods.
