Blue Slush Flavour Concentrate by Global Hubb is for use in DIY mixing and will require other ingredients such as PG and VG to use correctly. This flavour is reminiscent of a Blue raspberry ice slushy.
Flavour concentrates are designed to be added to a base mix of VG and PG, infusing a particular flavour into the blend. Users can add in as little or as much flavouring as they wish, allowing for either a strong or weak flavour blend.
