Harvested from the rapidly growing moso bamboo, bamboo charcoal is a naturally occurring porous structure with millions of microscopic holes pulling and absorbing odour and excess moisture. Bamboo charcoal is natural, sustainable, reusable and recyclable. Due to non-toxic and eco-friendly attributes, bamboo charcoal is literally nature’s way of eliminating life’s stinky stuff! The Drawer Packet Refills are completely unscented and eliminates odors instead of masking them. Simply place your deodorizers into any drawers, bins, or small spaces.
