This is some serious menthol. Allergies got you clogged up? Just glancing at this bottle will clear you up! (Joking! Sort of...) On a serious note, this is more menthol than any other menthol juice I tried. It may even begin to get menthol shards in it if it gets chilled. All you have to do is warm it slightly, body heat will do. This is an interesting vape, nice to add a drop or two to a tank of fruity juice to give it a menthol kick.
