SvoëMesto Kayfun V4

Wonderful rebuildable tank atomizer by excellent producers SvoëMesto.


One of the best RBA's on the vaping market today.

SvoeMesto’s Kayfun V4 rebuildable tank atomizer is the latest incarnation from the Russian company. They have completely changed that design and function of the hugely successful Kayfun 3.1 and have incorporated many new features and improvements over the 3.1 and Kayfun Lite.

Some of the new features include a design that allows top filling, a borosilicate glass tank option as well as the steel option and the polycarbonate tank option, quad screws for dual coil builds but our favourite feature is the fact that you can now remove the build deck without having to empty the liquid, so you can change coils or re-wick whenever you fancy and not just when you have emptied the tank like you once had to with the Kayfun 3.1 and Kayfun Lite.

Airflow was once a tad restrictive with the older versions of the kayfun but the V4 has addressed that now and has a much more universally accepted airflow rate.  

Built using the finest materials such as 316L Stainless Steel, the Kayfun V4 truly is a masterpiece of Russian design and German engineering.
