The Z Sub-ohm SE tank is a special edition tank that equips a child safety lock to solve your concerns. It comes with an innovative quick-change prebuilt coil system that creates the purer flavor and massive vapor with the GV mesh coil. Further more, the integration of direct top airflow and top-to-bottom airflow is available to generate big clouds and enhance nice airflow. The quick slide coil design makes the operation easy. The Z Mesh Tank adopts high-grade KA1 to ensure the dense vaping and the updated fill port absolutely lessens the liquid spillage while refilling. With the top refilling design, you can be comfortable to fill e-liquid without dirty hands. What's more remarkable is that the new z coils are upgraded to twice the lifespan of regular coils.
