The Longfill PG Pack consists of a 60 ml Herrera bottle that contains only 30 ml of PG-based concentrated flavor (Longfill PG) plus 3 10 ml VG bottles from Herrera, which can be 0, 9, or 18 mg of nicotine each.

To obtain the final liquid, you need to add the contents of the 3 VG bottles into the 60 ml bottle, shake it, and you're done!

To place your order, simply select the desired final nicotine concentration from the dropdown list, and we will send you the appropriate bottles to achieve that concentration.

The formula is simple: you need to add the concentrations of the three nicotine bottles and divide by 6.

You can order the following final concentrations:

0, 0.15, 0.3, 0.45, 0.6, 0.75, or 0.9 mg/ml.
