Vivid Vapours Clearomisers are made specifically for the Vivid E-liquid E-cigarette and are ready for use right out of the box. Simply fill with your favourite Vivid E-liquid, attach to the battery and you are ready to go. Each clearomiser contains two wicks to absorb the liquid which is then heated by an atomiser. Always follow the instructions on your pack, ensuring you do not under or overfill the clearomiser or visit our How it Works page for more information. We recommend changing your clearomiser every 2-4 weeks or whenever you change your liquid flavour as this will keep your vapour tasting its best. This multipack of 5 clearomisers will keep you going for a long time!
