The RAW Hydrostone is made from uncoated natural terracotta clay that has been fired in a kiln. It was originally developed to keep tobacco fresh on sailing ships during long journeys across the sea and is great for rehydrating your favourite herbs. Simply soak the Hydrostone in fresh water for five minutes then place it with your tobacco or herbs. Watch the attached RAW video for more detailed information. The RAW Hydrostone is 6mm wide with a 37mm diameter.
★★★★★Almost magicalI don't know how to say this without sounding like I'm lying, but I used this on some super old tobacco that I had laying around. Really dry, nasty stuff. I thought that it'd be fine after a couple of days in my pouch, but I was surprised that it only took about half an hour to revive everything to its former glory. I can't recommend this highly enough, and have even started referring my friends to buy some (With fantastic feedback)
