Caneverron's Pocket Dimension

You can open a small opening to a pocket dimension where you can store a designated item. The pocket dimension can hold no more than 5 lbs and cannot hold undesignated items. The pocket dimension is not viewable in any way. The pocket dimension cannot be dispelled, but the doorway you create to retrieve or return the item can be counterspelled. Nothing living can be a designated item and the item cannot be larger that a 3 foot cube. You can create additional pocket for different items. The first pocket dimension takes 1 hour to designate an item, and it will take 30 man hours, and 50gp worth of incense and chalk to create additional pockets for another item. It takes 1 hour to change the designated item.
