Review (5/5): great quality and enough for more than 2 years
I use this to mix ejuice, great quality and enough for more than 2 years :). I decided to get this bigger bottle and saved a lot more compared to smaller bottles. As far as I know PG and VG are safe for long periods of time put in a dark place at room temperature, around 70. It's the ejuice concentrated flavors and Nic that you don't want more than a 6 month supply to store.
