Flatbox (Magic Box)

A practical example of hypergeometry and hypermathematics, the flatbox appears to be a wooden box about 3' long, 2' wide, and two inches deep. It weighs eight pounds. The top of the box is a hinged lid.
When the lid is opened, the interior of the box is filled with impenetrable darkness. This darkness cannot be dispelled by any form of magic; it is a characteristic of the hypergeometrical topography of the box.
Although from the outside the flatbox appears to be only two inches deep, it actually has the internal volume of a box six feet deep. (Thus, it has a volume of 36 cubic feet.) The maximum weight that can be loaded into a flatbox is 500 pounds. No matter how much of its volume is filled, the flatbox still weighs only eight pounds.
Since the inside of the box is completely dark, the only way to retrieve a specific item is to feel around within the box. Finding an object this way takes 1d4 rounds.
There is a significant danger associated with the flatbox. If it is taken into an extradimensional space (such as within a portable hole), if it is teleported, gated, or transported via dimensional folding or any analogous method, or if it ever suffers 15 hit points of damage, the flatbox explodes violently. This explosion destroys all contents of the box and inflicts 4d10 hit points of damage on any creature within 20 feet (save vs. spell for half damage).
