The 10ml bottle of ElfLiq nic salt has the same e-liquid as the Elf Bar 600. 34 mouthwatering flavors to choose from, such as the well-liked Elf Bar Watermelon and Blue Razz Lemonade. In addition, it has nicotine levels of 5 mg, 10 mg, and 20 mg to accommodate most vapers. More value is added because each bottle yields the equivalent of five Elf Bars. Not only does it preserve the flavor, but it is also far less harmful to the environment than using disposables.
