Brew Box disposable vapes are created by popular UK-based e-liquid mixologists, Ohm Brew and a good option for beginners and experts alike. Arriving prefilled and precharged, these disposables are ready to use straight away and don’t require any maintenance. Each device delivers up to 600 puffs, which is enough to outlast 20 cigarettes. They contain 2ml of nic salt e-liquid in 10mg and 20mg strengths, so when your device runs out of e-liquid, you can just replace it with a new one.
