FLEX DualBox offers two cool looking options:
Tuck your tank inside for that elegant evening look
Or for safe extended travels, or use top 510 port for daily vaping & easy access to your fluid level.
This Mod also allows you to mount a tank inside (slightly loosened) while you vape your outside tank.
The dual tank feature is perfect for keeping two different flavors at your fingertips and
to always have plenty of ejuice available.
