The Pulse BF Box Mod by Vandy Vape was designed by Youtube Reviewer Tony B. to share his love of squonk mods with the vaping community. Constructed of lightweight Nylon and ABS, the Pulse BF Box Mod features a compact and ergonomic design. The 8ml food grade silicone squonk bottle and battery are encased behind two magnetic battery panels for accessibility and can be interchanged with different colored battery panels to personalize your device. By utilizing the included 18650 battery adaptor, users can choose to use either a single 18650 or 20700 battery to power the device.
