a German store called Nanu-Nana (the Germans here will probably know of it) sells these mini-chests that would remind me of AatP's treasure chest bag... if only they weren't so obviously cheaply made! They have flimsy-looking closures, threads sticking out of the seams on the pleather and similar defects. But from about 2 meters away they look pretty neat.
Do you think it's acceptable to use them as bags anyway outside of a Halloween pirate costume?
Here are some picture links:

They all look different because they come in several shapes and sizes. They're made of painted wood, pleather and metal (brass?) casings.
