An electronic cigarette case is a great way to protect your e-cig from damage and keep your products together so that they are not lost. Electronic cigarette cases sold at Vape Hut have a hard outer shell and pockets on the inside, designed to hold your products in place. If you are using larger parts, like 1000 mAh batteries and a Nova Tank, none of the cases may be quite long enough for the whole unit without taking it apart. However, you will probably enjoy the medium and large cases if you are using larger batteries.
