Store disposables in a cool, dry place. A drawer, a shelf, or a sealed container works fine. Avoid the car trunk and windowsills. Heat from direct sun can cause the e-liquid to thin and potentially leak. Cold isn't as big a deal, but extreme cold can thicken the liquid and affect the draw.

If you're storing for more than a week, keep them upright. This helps prevent the wick from drying out unevenly.
