Manufactured by Esbit®, these are the same burners used by the German troops in WWII. Designed to be lightweight, so it will not weigh down your gear. Great item to have along when hiking, camping or just put a couple in your bug out bag for emergency purposes. Made to accept the Esbit® or any other solid fuel tabs (not included). In a pinch I’d imagine you could probably use small pieces hot coals from your campfire. Use with your stainless/aluminum pots, pans and cups from your military mess kits. May have some minor corrosion, but still fully functional. Folds to approximately 4” x 3” x ¾” for compact storage. These are the original German made stoves. Price includes four stoves.
