Replacement coils, also called atomizers, or sometimes wicks, for all major brands of clearomizers (tanks).
Coils usually come in packs of 5, and need to be replace when you get a burned flavour, or repeated leaking, from your clearomizer. The life of a coil can grealt vary depending one its type, how often, and at which wattage/voltage it is usually used, but for most people they will last between 2 to 4 weeks.
You will find on this page coils for clearomizers by Aspire, Kanger, Joyetech, and more, as well as wire and organic cotton for your rebuildable atomizers.
