After demand and discussions with the fans of EFS System,
we present the tighter version of the EFS deck, for sake of mtl lovers.
Air inlet has been modified at 2*0.8 with the same philosophy of EFS, the Enhanced Flow System
of two tiny 0.4mm holes on the deck
that bring extra air to the chamber, creating a playful swirl depending on the draw.
For better and more detailed layering of flavor, the research did not stop there;
we also intervened in the style of the existing EFS chimney, creating a second version for the daring vaper friends.
