Finally... This exists.

You know how when you go to a fast food restaurant and you're enjoying your French fries and you think, "Boy, I wish this could be preserved in an airtight bag so I could eat them as conveniently as I do potato chips." Well, they've done that. Although you can accomplish the same thing by putting leftover McDonald's fries in a grocery sack, tying it in a knot, and eating them a month later.
