Marius Fabre savon de Marseille, because no one should need to buy more than one bar of soap for the rest of their life. LOL. Seriously, this is a big bar of soap, at over 10 oz. Heck, it's not a bar, it's a huge cube of soap. I used it in the bathtub, and the soap is very mild scented, made from olive oil. It's a welcome addition to the regular rotation.
