The Elf Bar 4-in-1 prefilled pods are designed to be used with the Elf Bar 4-in-1 Pod Kit. Each pod is prefilled with 2ml of salt nicotine e-liquid in a 20mg strength. You can ensure a smoother throat hit and faster craving satisfaction thanks to the salt nic. As they are MTL (Mouth To Lung) pods, you can also expect a smaller amount of vapour that feels similar to a cigarette inhale.
