Cloud Vapor
Cloud Vapor is a French manufacturer of e-liquids but also of flavour concentrates for e-cigarettes. Cloud Vapor's e-liquids are used straight into your e-cigarette. As for the concentrates, they must be combined with a PG/VG base to create an e-cig liquid that you can use in your equipment.
Thus, you will be able to vape premium recipes mixed with the base of your choice, by dosing these propylene glycol and flavouring-based products from 15%. They are available in 10mL dropper bottles.
