Dimensional Lock-box

You send an item into a small space in the astral plane protected with force wall. That space can contain up to 8 ft squared in a 2*2*2 feet area. It costs an action to reach into and pull something out of this space. However, it only costs a bonus action to put something in. You can attempt to store an item that is held or worn by making an attempt to touch roll against their armor class. If you succeed in touching, they must make a Charisma saving throw. On a success, nothing happens, if they fail, the spell succeeds. This attack will deal no damage. 

The pocket can hold up to a maximum of 65 pounds. There is no air in this space. Creatures contained in other items are released within 5 feet of the caster. This space can be accessed by use of spells like plane shift.
