How long do Chinese fortune cookies last?

Excuse me, could you please clarify something for me? I've been wondering about the shelf life of Chinese fortune cookies. How long, roughly, can one expect them to stay fresh and edible? Is there a specific storage method that prolongs their lifespan? Or are they more of a 'consume as soon as possible' type of treat? I'm genuinely curious about their longevity and would appreciate any insights you might have on the matter.
