Drag Bar BF600 disposable vapes are designed with easy of use in mind. You don't have to worry about dealing with buttons or settings, instead you can just just inhale on the mouthpiece to start vaping. When you do, your device will create a smaller amount of vapour for an MTL (Mouth To Lung) inhale. These vapes arrive in a handy pack of two, and each one is prefilled with 2ml of 20mg of nicotine salt e-liquid, delivering a smooth throat hit and up to 600 puffs.
