I decided to try it and I'm a miracle. I ordered it back in 2013)) The plastic cover is unscrewed, and inside is a translucent stone. In order to use it you need to moisten it with water. He does not have a smell at all and I consider it a plus. For those who sweat profusely-not suitable. For example, if I go to an event, I still use the usual antiperspirant, since this miracle stone can not give me 100% confidence. Yet in this respect, he loses. If you have cuts or you have just shaved your armpits, it is better to refuse it, as it will pinch (due to its salt composition). How much is it enough? It seems to me he is eternal!)) He still lives on my shelf in the bathroom.)) If my feedback was useful to you, press YES. More reviews- on my page, go to that one by clicking on my name. Successful and fast parcels! :)
