First bar (Pine Tar) has been used only at bath sink for hand washing for myself alone - one person. It has not lasted anywhere close to the 3 months i heard from the person I learned about Kreamy Soaps from. The bars are much too small for the price though they are seriously luscious. I bought some little natural fiber bags to put the soap in to help with longevity. Doesn't help really. Any chance of enlarging the bars to double the size?
