The amount of puffs in a Crystal Bar depends on the e-liquid capacity, as well as your style of vaping. There's the Crystal Bar 3500, which offers 3500 puffs. There's also the Crystal Bar 4000, which can offer up to 4000 puffs. However, if you find your Crystal Bar running out too quickly you might benefit from making a bulk buy. At Grey Haze we offer a multibuy offer where you can purchase packs of 5, 10 or 20 Crystal Bars. We also offer loyalty rewards for every purchase.
