This beautifully designed tank is a product of the brilliant minds at Vaporesso. The Veco Tank is an incredible addition to any vaping arsenal and will provide incredible clouds of vapor. It has a simple to use top fill feature that allows you to refill your tank without tanking it apart. Not only can you fill it from the top but you can adjust the airflow from the top as well. The airflow feature allows you to personalize your hit of vapor by limiting or expanding the airflow allowed through your tank. All with the simple twist of the top! The Veco is a bottom coil tank meaning the coil is accessed and changed through the bottom. This makes coil changed easy and assures that your coil is continually saturated.
