Made in Italy by the Mod Factory the K-Nano steel setup replaces the top and bottom steel tank sections on your Kayfun V3.1 and Kayfun Lite/Lite Plus series atomisers. This kit reduces the overall length of the tank section by 10mm. The set comes with a shorter chimney section so all of your 510 drip tips will still fit, yet is still long enough to use only one of the K-Nano steel sections for a middle size setup.
