The Elf Bar 600 has been designed to be simple to use. It uses draw activation, which means it fires as soon as you take your first puff. With no fire button, the Elf Bar 600 cannot be accidentally activated while in your pocket or purse. The 2ml of nic salt e-liquid is held in a leakproof tank and is delivered to the optimised coil as you take a puff, providing just the correct amount of e-liquid for the perfect vape experience.
