This bag has an interior space considerably larger than its outside dimensions. The bag can hold up to 5 small plants 3 medium plants and one large plant. The bag weighs 5 pounds, regardless of its contents. Retrieving an item from the bag requires an action.

If the bag is overloaded, pierced, or torn, it is destroyed, and its contents are scattered in the Astral Plane. If the bag is turned inside out, its contents spill forth unharmed. The bag holds enough air for 5 small plants, 3 medium plants, or one large plant for one day.
