Kayfun 5 PEI Tank
The PEI Tank Kit for the Kayfun 5 is a tank version of compromise. A viewing gap on the bottom side of the tank provides certainty about the tank contents without losing the steel tank optics. Matching the viewing gap, the kit includes a tip insert for the Drip Tip of the Kayfun 5 made of the same, robust plastic material (polyetherimide).
Not usable with extended Kayfun Prime!
