So what are soap nuts anyway? Soap nuts are actually the dried shells (or husks) from the soapberry nut, which come from the Sapindus mukorossi tree—a unique species of trees found in both the eastern and western hemispheres, but native to the tropical conditions of India and Nepal. Even though they are called nuts, they are actually dried berries, making them a safe option for people with nut allergies. This formula will allow for approximately 185 wash loads per one pound of nuts. ***This item is only available for in store pick up***
