The NRG GT coils come in a pack of three, where you can pick exactly what resistance you want from them. The Vaporesso coils use traditional cotton to give your eLiquid an even vaporizing process, though the traditional cotton is heavily inspected to ensure that it is the best quality possible. The structure of the NRG GT coils is made using their c-Cell Ceramic, a specially formulated ceramic that is more durable than many other ceramics used.
Caution: These coils are low resistance sub-ohms coils. Which can be dangerous if you are not using the correct equipment. You must be sure that your device and batteries can handle sub-ohm coils. Please use 20 amp or higher batteries.
