All things being equal, if you would like the least hassle and minimal inconvenience, storing your cartridges mouthpiece up, is the best way to go.
A simple way to accomplish this is to keep all of your cartridges in your PurToke Vape Pouch and simply find a place to prop it up.
Storing your cartridges in your Vape Pouch and keeping it in your pocket or purse is also an excellent way to go. Just remember, the tag is at the top of the Vape Pouch so keep "The Tag at the Top" when you place it or prop it somewhere.
