As long as your treasures aren't too big, of course. These aren't full scale replicas. But they're awesome nonetheless.
The designer is one Heather Marie, a Pennsylvania-based craftsman, who sells the chests through her Etsy shop at $US80 a piece. They are hand-made using quarter-inch pine plywood, with engraved decorative designs on the exterior and a crushed velvet lining inside. They come in three flavours: Horde, Neutral, and Alliance.
As for dimensions, each chest is 20cm long, 19cm wide and 18cm tall, so they're not exactly just paperweights -- but they're not massive, either. Here's a few more photos to give you a better idea:
