The CL tank from KangerTech is a revolutionary tank designed with safety in mind. A top locking mechanism attached to the top cap helps to keep the tank securely sealed and prevents tampering. The atomizer chimney is connected to the top cap for easy top-fill capability while preventing vape juice leakage. By twisting the ring section at the top of the tank users can adjust airflow. A 22mm tank diameter provides users with plenty of room for coil installation. Built using high-quality stainless steel with a Pyrex glass tank.
