I ordered this for my tank eGo-C and am very satisfied. The tanks can be filled with different liquids to have a first, since they have a silicone cap at the bottom and thus not leak. When filling the tank, but you need refill with a tip that needs to be considered when buying the Liquids. The tanks are individually wrapped in a foil and they are delivered in a cardboard box. The shipment went super fast and was within three working days with me, thank you, happy again!.
