Finely ground Walnut Shells make an extremely stable and effective exfoliant. Walnut Shell Powder can be added to soaps, scrubs, or even fresh exfoliation treatments. This pale tan powder is available at FromNatureWithLove.com in two different grain sizes. Our Medium Walnut Shell Powder is superb for pedicure scrubs, crafter’s soaps, or any other formula that requires intensive scrubbing and exfoliation. Though the Fine Walnut Shell Powder is equally as hard as the Medium, it has a smaller particle size, making it a better choice for body or facial scrubs.
