All our Longfills contain either 20ml of 50VG/50PG concentrate in a 60ml bottle or 40ml of 50VG/50PG concentrate in a 120ml bottle. By filling up the bottle with base mix and nicotine shots (if required) you can make an e-liquid at your desired strength.
The basemix and nicotine is sold separately.
