Flavorless e liquids also known as flavour free vape juice, are e-liquids and vape juice that do not have any added flavorings.
They are typically used as a base to which users can add their own flavorings, or as a way to add nicotine to shortfill liquids. This flavourless vape juice can be vaped alone and is extremely popular for vapers which find some flavours too much to vape all day.
They are made up of a mixture of propylene glycol (PG) and vegetable glycerin (VG), which are the main ingredients in most e-liquids. They are also available in nicotine-free version.
