Filling your sub ohm tank could never be easier! Now featuring a top fill design for easy refilling, the Starre Pro Sub Ohm Tank by Starre will make tank filling an easy process. Located at the drip tip is the adjustable airflow to provide a little more air to those vapers who like a loose draw. The primary airflow for this device comes from the bottom base. This airflow consists of two large cyclops style airflow slots that have even better airflow that the original Starre Tank. A dual vertical Ni200 coil is what gives you your superb flavor with this unit. Stock with a 0.15Ω Ni200 head, these coils may be able to handle from 20 watts to 100 watts! Wicked with organic Japanese cotton, the flavor off of the Starre Pro is fantastic.
