Monster Bars are disposable vapes created by US-based e-liquid manufacturer, Monster Vape Labs. These vapes are ready to use straight out of the box and with no maintenance required, as well as inhale activation, vaping is simple and hassle-free. Each device is prefilled with 2ml of salt nicotine e-liquid for a smooth throat hit and fast satisfaction, and will deliver up to 600 puffs. This means they’ll easily outlast 20 cigarettes.
