The newly added BFHN 0.5ohm coil head is now optimized for use with high nicotine liquid. It supports mouth-to-lung inhale. The injection of high nicotine liquid or nicotine salt is bound to provide the best vaping experience. The low power consumption allows the battery to have a very low output, which extends the battery life doubly.
NB: Each sold separately, per coil NOT per box.
