The refill liquids (e-liquids) of electronic cigarettes are vaporized and give us the taste as well as the sensation of smoke. They consist of a “vapor base” (or plain base) containing propylene glycol (PG) or vegetable glycerin (VG) or a mixture of both, as well as distilled water and are very economical as their prices are relatively low. The vaping base that contains nicotine is called "nicotine base" or nicotine base. The base usually makes up up to 90% of the evaporating liquid. The remaining 10% usually consists of aroma/flavor. At SmartSmoking you will discover the largest variety of wonderful and unique flavors that will take you on a journey. Make your own refill fluid easily and quickly. You choose a scent, add nicotine booster and base, SHAKE and VAPE!
