Abstract: A portable, stackable, all-in-one, combustible fuel package composed of a carton without internal structure and containing a fire starting material and charcoal or other combustible material, a one-piece carton blank for forming the carton, and methods of assembling and using the carton and its components to provide a heat source are provided. The carton blank is a simple design for easy assembly of the carton. The container maintains the firestarter separate from the charcoal material and allows direct access to the firestarter for its removal from the container. The carton includes selectively deployable legs structured to raise the carton off of a surface sufficient for placement of the firestarter under the carton and allow air flow to the base of the container to maintain the burning of the firestarter and charcoal material inside the container.
