Elf Bar BC5000 disposable vape is among the most advanced and potent models on the market. The Elf Bar BC5000 is small and light enough to easily carry in any pocket and is shaped like a little box mod. Yet with its incredible 13 ml capacity, it has plenty of vape juice to last you a long time. It simply consists of a vape pen as well as a bottle of e-liquid, and given how long it lasts, the price is surprisingly affordable.
