The Kayfun Lite Plus V2 is a new version of the Kayfun Lite Plus which now features adjustable airflow and improved overall build quality! On the bottom of the tank, next to the fill screw, you will now find a second screw that will open or close the airhole, allowing you to get the precise draw you're looking for! The Kayfun is a rebuildable atomizer designed to enhance the flavor of your juice. It uses a chamber to house your wick and coil, which concentrates the vapor and produces a bold flavor. The Kayfun is made of stainless steel with an optional clear polycarbonate window so you can see how much juice is remaining. Because the Kayfun Lite is rebuildable, you can achieve your perfect vaping experience. The Kayfun Lite comes with everything you need for your first build, along with replacement parts.
