STAR REMEDIES PURE, a natural mineral salt that occurs naturally in nature that has been used for centuries. A source for a natural deodorant. PURE is the world's only 100% natural deodorant. Use: Do not dry the skin after washing. Take the crystal and go gently with it under the armpits a number of times. If the skin is no longer wet, make the crystal a little wet under the tap. A microscopic layer of the crystal will now remain on the skin and will neutralize the bacteria that cause the unpleasant odor. Simple and easy to use. The deodorant will certainly last for 1 year. Calculate the benefit yourself.
