The Trangia Multi-Disc can be used as a cutting board, serving dish, strainer, or as a base for your storm cooker on snow, mud or soft sand. It can also be used to cover food following cooking to keep it warm. The Mutidisc is a must have accessory for the series-25 3-4 person and series-27 1-2 person Trangia stoves as it will also stow neatly inside your cook set and protect non-stick coatings during transportation. *Do not use as a lid for pans or pots while cooking. High heat will damage the product.
