Cool Crush - Blue Raspberry slush with an element of subzero On the inhale you get the distinct Blue Raspberry Slush followed by a burst of subzero that brings the other berries to the fore. Its not too chilled but just enough to make this an amazing all day vape. The smooth exhale carries every note of this remarkable flavour. The aftertaste is like you have just had a drink of Blue Slush straight out of the machine. It really is that good!
