I store it in 90% filled pods stacked on a top shelf in my office room in the house. Steady temperature, always in shade, and I "shake" them about two times during te winter.
i have mine in a plastic Tupperware container one like for cereals. with silica packets like you get in shoe boxes, to keep moisture out. but i don't usually keep it for more than a month
i store mine in a thermal bag and turn the paint at least once a week so that the ink does not dry all at the same side.
try to use it in a month time.
keep mine in a coolbox obviously without the ice packs just find it a nice sealed container to use but as mentioned above i feel that turning the paint is a good idea
