OK e-liquid features a solid selection of fruit, menthol, soda, candy and tobacco flavours. Blended to create a vape that feels closer to a cigarette, they use freebase nicotine for a stronger throat hit and are available in strengths from 3mg - 18mg. They also feature a 50% VG concentration, which creates a discreet level of vapour. They work best with MTL (Mouth To Lung) vape kits.
