Quick coding project based on sprites made by someone in the thread in response to a request for a PMMM (anime) reference item. While inactive, just behaves the same as a regular item. Can be clicked to be made active, which will allow it to be used as a storage device and give the user the ability to draw from it. Capable of storing and weapons and explosives when active. Acts as a pocket dimension, and so has no weight or size limits.
