As an action while in possession of a formula scroll, you may use this jutsu, storing an amount of objects you are touching that are not in possession of another creature inside a formula scroll depending on the size. Scrolls, Handy haversacks, and bags of holding cannot be stored within scrolls, if attempted, the attempt fails and the scroll, and any of its contents, are destroyed.
