The Elf Bar 5% Disposable Vape is a type of electronic nicotine delivery system (ENDS), commonly known as a vape or e-cigarette, which contains 5% nicotine. ENDS work by heating a solution, known as e-liquid, which produces an aerosol that is inhaled by the user. Elf Bar is one of the most popular brands we carry, and for good reason! These vapes are super easy to use, super tasty, and look super cute, too.
