The Tallboy is a tank for the Stubby Aio offering the flavors of a rebuildable atomizer thanks to an exceptionally careful design and the coils of the VC Tech platform. 8.5ml capacity and convenient filling from the front of the tank. Very precise adjustable airflow allowing you to alternate between MTL and DL draw. Magnetic tab allows the tank to be easily removed from the Stubby Aio. Original “double tank” design.
