I know blue isn't a flavor but what I do know if that anything that has a blue coloring to it seems to always never fail you. Blue Razz Ice by Air Factory is pretty much the same when looking for a fruity candy based vape juice twisted with mint. It's well known and commonly reached for when spotted out of the vape candy bucket.
Blue Razz Ice is basically like sucking on a blue raspberry hard mint candy with the exact taste of the sweet and tart delight that revives the inner child on those taste buds. On the inhale you'll experience the thick cloud carrying the luscious flavor of blue raspberry on your tongue, while the tartness of the hard candy flavor escapes on the exhale leaving just the sweet aftertaste and aroma of blue raspberry candy in the air.
I don't know why blue is such an amazing "flavor" but it is and it's a safe bet in any case or situation. So why can't it be the same for Blue Razz when you pull up candy results for vape juice, Air Factory definitely lives up to its name and you will not have any regrets. Just you, your vape, and sweet sweet Blue Razz vape juice. You know what they say, if it's blue it must be true.
