For snack lovers, particularly crisp lovers like myself you're in for a real treat!
Calbee have released a new type called Jagabee, which are crisps designed to look and taste like chips, but aren't chips. They are different, and something to experience, but I personally find them a little salty and harsh on the throat, but they do their job of looking and tasting like chips! Oil factor / health factor I'm not too sure of which is better out of crisps / chips, but I know one thing for certain...
They're both potato.
