The fine thread for the Premium Nargile (PN-Shisha) has to be spinned ca. 8 times, befor it closes. On one hand, that's annoying, on the other hand unneccessary friction causes much wearout.
Kaya Shisha is therefore changing to use the newer and coarser thread 2.0, but of course, we still supply the fine thread 1.0 for the older smoke stems.
