All of our soap is made with olive oil for an extra mild bar. Unless you have ultra dry skin, the use of our soap alone should moisturize your skin as much as applying body lotion does after using a bar of commercial soap. One bar of soap should last one person at least three weeks if they keep it high and dry in-between uses. Never let it sit in a wet soap dish because it will melt! Cost is based on the ingredients used; blends rotate on a regular basis. Custom batches available with a 12 bar minimum.
