optimus gas cartridge contains a high-quality gas mixture of propane, butane and an increased amount of isobutane, which is particularly resistant to low temperatures. Even at temperatures close to the freezing point, stable performance is ensured to reliably operate gas burners at any time of the year, as well as at high altitudes.

The cartridges are protected from damage by an innovative valve that also indicates whether the cartridges are used or new.
