FUM is a "flavored air" device designed as a natural, non-electric alternative to vaping and smoking.  It uses no batteries, no liquids, and produces no vapor.  Instead, users inhale through a weighted wooden barrel containing a medical-grade polyester "core" infused with essential oils.  It is designed to replace the hand to mouth fixation of smoking and features a textile "fidget" component - like a clicking barrel- to help manage nervous tension and cravings.
