This bag has an interior space considerably larger than its outside dimensions, similar to the interior of a Bag of Holding. The bag weighs 15 pounds, regardless of its contents and the conditions inside the bag are suitable to comfortably keep plants, food, and other similar objects for indefinite amounts of time. Retrieving an item from the bad requires an action.
If the bag is turned inside out, its contents spill forth, unharmed, but the bag must be put right before it can be used again. Breathing creatures inside the bag can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate as the environment inside is only meant to sustain plants not people, Casper please do not climb inside the Bag of Preserving.
