Crystal is my preferred product. I have been using it for years. This is the first time I am using one that is not encased in plastic. Cork? Wow. I like the way this product works for so many hours. A bit more pricey, but, worth it.
If you dont drop it, it could last for years!

perfectly packaged and pricey.

I got this because the other brand I used to get deodorant from only offers smaller sizes now, so I figured I should try something else. I did not pay attention and realized that this is an actual stone, a crystal. Was very confused as first and didn’t understand what I was supposed to do with it. But after some research I understood the purpose of it and if it really worked the way people said it would, I would be very happy, this thing would last me at least a whole year. I recommend you try doing a deodorant detox routine while using this for the first month, otherwise your transition might not be as smooth. I used Indian healing clay, apple cider vinegar and a few drops of tea tree essential oil (mix the clay and vinegar till you get a good consistency, probably start with 1 tablespoon of clay and 2 teaspoons of vinegar), but you can also look that up. While doing this detox routine I could already see results, the crystal suppressed the smell from being spread in the air, I still get a little bit of it but it’s like dry on my armpits and I can’t smell it unless I bring my nose up to it. Obviously this deodorant is odorless, so I personally started making a little mix of water and essential oils when wetting the stone, just make make sure you don’t use too much essential oil because it might cause skin irritations. Excited to see the evolution with this product

My last deodorant was from Lavanilla. It was ok but I still broke out under my arms a bit. Not as bad as traditional deodorant (especially because of metal allergies), and I have super sensitive skin. And unfortunately it is in a plastic and I had to scrape out the rest when it got to the bottom. Though it did smell good (which I loved) it wasn't worth still irritating my skin. So when I switched to biork it was life changing! It is a lot more effective and long lasting (in both usage through the day and how long it last over months). And my under arm irritation completely cleared up! I thought I would never find a solution! I am so glad I won't have to risk scarring or feel uncomfortable under my arms anymore! Or anywhere else! During the summer I also use it in the fold of my thighs, under my breast, and in the folds behind my knee caps. And still no irritation! It still works just as well!
