Our soap is made of vegetable glycerin and essential/fragrance oil, depending on the scent you choose. They are firm, durable, and will keep their scent for as long as you use them. We hand-pour and slice every piece right in the US! Truly, our soaps feel as good as they look and leave you very moisturized with no icky film feeling left behind on the skin. They make great gifts, whether for yourself or your friends!
