If you have a SMOK Novo kit, then you are in good hands. the SMOK Novo Cartridge is very easy to use as all you have to do is remove the rubber stopper from the side of the cartridge to fill it up. Once you have put your E Liquid in, replace the rubber stopper and make sure it is tight. If this is the first time using the pod, you ought to leave it be for 10 to 15 minutes so that the wick can be thoroughly soaked. The SMOK Novo Cartridge is designed specifically for the Novo pod, and if you own one it can be great to have these as replacements and spares.
