The Dewbie is a unique product with one distinct (and important!) function. It is technically a handmade, all-natural humidity stone (made of clay) that works to rehydrate stale herbal material. Stupendously easy to use and clean, you will wonder why it took you so long to get one! Remember that time you found some herb that you had forgotten about? A happy occasion that can be tinged with a little sadness when you realise how stale and overly dehydrated it had become. In the past I would have used a Boveda pack to rehydrate (still a good option), but now I have the Dewbie.
