The Watermelon Ice Lost Mary BM600 disposable vape is built to be convenient and easy to carry around with you. Plus, we?d recommend it to vapers of all experience levels, because it?s so simple to use. You won?t need to change any fiddly coils or refill with e-liquid, just replace the old device with a new one when it?s run out. Beyond that, there?s 600 puffs in each device - more than 20 cigarettes would provide.
