The Elf Bar Elfa prefilled pods are designed to be used with the Elf Bar ELFA Pod Kit. They each store 2ml of E-Liquid and provide up to 600 puffs per pod. You'll get a smoother throat hit and quicker desire fulfilment since they include salt nicotine. They're also made to provide an MTL (Mouth To Lung) inhalation with a low quantity of vapour and a cigarette-like sensation.
