I swear by this product. If you don't believe me you can ask Mark. And if you don't believe Mark you can ask Mike since he's the one that introduced Mark to the crystal deodorant stone.
I stopped wearing deodorant years ago because of the aluminum and chemicals that came along with it. I chose to go the "natural" route with Tom's of Maine which is good but nearly as good as this. I dare you...try it and you will be pleasantly surprised. I heard it lasts a year which is way cheaper than buying deodorant. Think of it as the $6 funkless, natural pit!!! No more white marks on clothing although you will sweat a little bit since it's not an "anti-perspirant" but it's healthy to sweat out your toxins anyway right?
Let me know what you think!
