How long would unopened motoyama roasted dried seaweed sheets keep and still be edible?

Question:

while clearing out our work kitchen, we found several unopened packages of roasted dried seaweed sheets. I remember us orderign them 4-5 years ago for a party where we made sushi rolls. there's still so much left and if it's still good there's people here who would gladly take it. But no one knows seaweed shelf-life adn there's no expiration date. I say it's safer to chuck it, but frugal folks fuss. So yahoo users; yay or nay?

Answer:

There air tight, have a silica gel packet in them, salt cured they can last for years, sometimes over time they can degrade and fall apart, but crumbled and mixed with sesame seeds, chili flakes, Japanese pepper seasoning and a bit of garlic flavouring you can use it as topping for rice, in Japan and I worked there Furukake is a very popular item, like ketchup and bacon bits in the west.
