About four years ago, I started to use natural deodorant. I discovered a lot of pluses. Firstly it is a deodorant and antiperspirant. It does not prevent sweating, but eliminates the smell of sweat. Leaves no residue on clothes. No odor, can use it for both men and women. Very economical. As you can see, a lot of pluses. Prior to use, it should be wet, and here is a point that the crystal becomes slippery and can fall and break. I broke all-time use only and one other company. It is this crystal is very reliable and easy to use. I recommend, I think this product should be many in the family If my review was interesting for you, please click, "YES" at the bottom.
