Medium size gas cartridges for all Campingaz stoves and lamps with Easy Click connection. The butane/propane gas mixture burns well in three-season activity. The Campingaz CV Plus valve cartridges are equipped with a self-closing safety valve. This means that the stove and lamps can be removed from the cartridge even if it is not yet completely empty, giving you the advantage of being able to transport and store the cartridge separately or operate different devices in succession on one cartridge.
