You flick your wrist with a flourish, causing a single object that weighs no more than 5 lbs that you hold within your hand to vanish. The object is actually transported and stored within a small extradimensional pocket plane. The object remains there indefinitely until this cantrip is cast again, upon which it is immediately transported back into your grasp. You cannot store an object while one already occupies the extradimensional pocket.

(Note: I made this spell so more classes can use it, Artificers, Warlocks and Sorcerers shouldn't miss out on something a tad special like this in my opinion)
