Blue Razz by Air Factory E Liquid has a sweet blue raspberry inhale, with a sweet candy tart exhale. It has an extremely smooth and enjoyable throat hit. It feels stellar to vape on, it is in no way harsh or uncomfortable. It is one of the best feeling hits we have had in a while. Blue Razz by Air Factory E Liquid comes in 70%/30% VG/PG blend which means you are going to get some serious flavor as well as decent cloud production.
