10ml Vape Juices are typically for smaller kits, including pen style kits and starter kits such as the T18E Vape Pen or the Arc 5 Starter Kit. This is because they’re mainly a 50/50 ratio of VG and PG or a 60/40. This is considered a “thin” mix which smaller coils which are higher in resistance (ohms) can restrict through. Using larger kits, which coils often have larger holes in, will likely lead to flooding, leaking and a a bad vaping experience.
