Mr Berg - K-TPD 4 mL
K-TPD is the intelligent system that allows you to reduce the tax impact on ready-to-use liquids (in countries where it is intended).
MINI LONGFILL 4+6 K-TPD are pre-mixed e-cigarette liquids without nicotine. 10 ml bottles contain 4 ml of aroma. Add a dedicated K-TPD base with or without nicotine to get a 10 ml ready-to-use product. In Italy you save 40% of the tax using the base with nicotine and 100% of the tax using the base without nicotine. You can also use ZERO boosters to get a product with HIT but no nicotine.
If you want more information on the composition see the tab "how to prepare"
