The amount of time it takes me to open the envelope and dump it in my evod.
In all seriousness, I am curious too... I got my first 6ml as a sample...Loved it and blasted that in a couple of days. Ordered my second, a 30ml, the day I got the first 6 since I loved it so much. That one lasted until 9 days until today, when I just got another 30 today

(along with a 30 of Huntsman and Dipity)...
They are airing out now (well, other than what I put into my
tank and evod) and I'll give them a nice hot bath to speed things along when I get home.
