These are replacement insides for our Clearos and Carto Tanks. The insides will not last forever, but these are the only parts that need to be changed out occasionally. When you do, it is basically like getting a new tank. These generally come in different resistance levels, which are measured in Ohms.
These are extra mouthpieces that allow you to customize the look of your vape. These can be used on devices with replaceable drip tips. These generally do not effect performance one way or the other. They are called "drip tips" because people would put them on the end of a cartomizer and drip into the cartomizer through the tip.
These are unregulated battery tubes. They are basically metal tubes that hold your batteries and allow them to fire. There are no computer chips or protection with these batteries. These are usually used with Rebuildable Atomizers. Caution must be used with these devices, but the rewards can be great!
