The Clearomiser is filled by simply unscrewing the base and adding e-liquid directly from the bottle. Items ordered before 9am are guaranteed to leave the same day, items ordered before our 3pm cut off are also more than likely to go the same day. Postage is royal mail 1st class so should be with you the very next day, recorded delivery is available at request although a small charge will be incurred, please contact us if you require this service. Our aim is to keep prices down for the customer, therefore we believe RM 1st class to be the best option. Please note: Make sure the small atomiser head is fully tightened into the base before first use. The price is per clearomiser of your chosen colour.
