The Horizon Falcon King Tank is an updated Falcon that holds up to 6mL. The Falcon King is compatible with the new Falcon coils, M-Dual 0.38ohm mech coil and M1+ 0.16ohm mesh coil. Both of them are made of bamboo fiber, which produces better flavor and has a longer lifespan. The Falcon King is also compatible with all Falcon coils, and has a new top fill design. Airflow enters the Falcon King Tank via adjustable bottom slots and can be fully closed.
