Crystal deodorant is made with mineral salts, so it creates an anti-odor barrier to help stop odors at their source. This effective odor fighting stick is not sticky or staining. It is ideal for both men and women. This deodorant is ideal for the underarms or the two sweaty areas of the body. Plus, it`s fragrance-free and comfortable for even the most sensitive skin types - and it doesn`t leave any white marks!
