Futurola pre-rolled cones are loaded into the Cone Loader, which is then placed on top of the Flling Kit. Load your material into the Mix Tray, turn on the Knockbox with the controller,  and pull the metal slat to release your material into the cones and watch them get filled in just seconds! Our Knockbox Machines have been used all over the world to quickly load our artisanal pre-rolled cones with healing herbs and medicines.
