Deodorant Crystal - 120g - Biork

$18.00 USD

 A completely ecological, 100% natural mineral crystal that is truly UNIQUE as it's the ONLY crystal stick deodorant I have ever seen packaged in cork!  What a brilliant idea! 

Biork deodorant crystals are made of a natural mineral salt called potassium alum which has been shown to have antimicrobial properties.  Potassium alum has been used as a deodorant in Southeast Asia for hundreds of years.

I have exclusively used deodorant crystals since I was a teenager when they were only available as raw rough shaped crystal 'rocks'.  I was relieved when they eventually became available shaped with a nice smooth application surface in a conventional plastic deodorant casing.

I can't tell you how thrilled I was when I finally found this totally plastic free option.

These come all the way from Switzerland and I'm excited to be one of only a few shops carrying them in North America.

With daily use 1 should last 6-8 months.

There are so many ways to repurpose and reuse the cork container; cork is particularly suitable for cacti and succulents.  Great for kids crayons, jewelry when you're traveling, paperclips in the office.  The list is endless!



  • 100% natural and antibacterial
  • No aluminium chloride, aluminium chlorohydrate or other toxins
  • Unscented
  • Dermatologically tested to prevent skin irritations
  • Vegan
  • Cruelty free
  • Invisible when applied
  • Zero residue on clothing
  • Packaged in renewable and recyclable cork from Portugal
  • Tons of ways to repurpose and reuse the cork container
  • So easy to apply: wet the top, rub on skin & you're done!



  • Super simple:  quickly wet the top (I flick it under the tap like wetting my toothbrush) then rub on!



  • As you apply, count to 15.  This is 100% effective IF you apply enough of it.  It's not like conventional roll on deodorant where 4 or 5 swipes in 3 seconds puts a lot of product on.  I rub vigorously for the full 15 seconds.  It feels like, well, like you're rubbing water off a wet rock under your arm (which you are) and it is magic!  There is nothing to see, nothing to smell.  Nothing to rub off on your clothes.
