This thick iron plate, made of black iron, can be used outdoors. The possibilities are endless, and it can be used for solo camping, mountain climbing, and more. Features: Once the iron plate is heated, even low heat can sufficiently cook ingredients due to the plate's heat retention and radiant heat. Thin iron plates have poor heat retention, requiring high heat to cook ingredients. This results in the surface burning before the inside is cooked. The heat retention of 4.5mm, 6mm, or 9mm thick plates is considerable.
