Basevæske - 10ml.
This 10 ml. 18mg. base liquid is typically used for mixing with your 0mg. base to achieve a strength between 0 and 18mg. in your finished base.
If you want an 18mg. mix, you can simply unscrew the lid and add up to 2ml. of flavouring (20%) directly into the bottle. Shake the bottle well. It's easy!!
The liquid should preferably mature for a few hours/days before use.
Normally, pg/vg bases are mixed with about 10% flavouring (which is pg based) to add taste.
