The EHPro Kayfun Nano is a rebuildable tank that offers the same vaping experience as our other Kayfun tanks with a smaller profile that's not so invasive. The Nano has all the same features as the Kayfun Lite Plus, including adjustable airflow, except it's about one half-inch shorter. This is acheived with a shorter chimney section, allowing a shorter tank tube to be used. However, the capacity is reduced to about 3mL. This kit will come with everything you need for your first build, along with 4 translucent tank tubes: colorless, blue, green and purple. The overall size of the Kayfun Nano is comparable to the Smok PBC tank. Like other Kayfuns, the Nano uses it's evaporation chamber to concentrate the vapor, which produces a bold, true flavor that is yet to be matched.
