Daern's Instant Cheese Shop: one of his prototypes, this item expands into a cheese shop, containing an animated puppet dancing to music of unknown source, and a servant of pure force who is there to serve you cheese.
There is no cheese to be had within. Daern did not stock it. But if it is stocked by the shop's owner, there will be cheese to be had. Any other foodstuffs placed within will go bad, but cheeses of all kind will remain edible for at least a year. Its total storage capacity is unknown, however, since no known owner has ever tried stocking the store with cheese.
