Puff Bar presents the Puff Flow, an 1800 puff disposable vape. The Puff Flow is a larger capacity version of the original Puff Bar, packing in a 850mAh battery and 6.5ml of 5% TFN salt nic vape juice. These non-rechargeable disposable vapes are as easy to use as the original, but have an adjustable airflow control ring so that the user can adjust the draw of the device.
