The Advken Manta MTL 24mm RTA is an innovative mouth-to-lung rebuildable tank atomizer, featuring a dynamic single coil build deck configuration, auxiliary bottom airflow control, and a threaded top-fill system. The Manta MTL RTA comes with the standard 2mL glass tube, but can be upgraded to a 3mL bubble glass tube that is included. The build deck is expansive and features a gold plated finish to ensure the best possible connection and conductivity. This connection makes the Manta MTL RTA very reliable. Furthermore, the knurled and threaded top fill system is easy to access and grip, turning to reveal dual fill ports to accept today's most popular eJuice for a long and satisfying vape experience.
