What was the most packed school lunch sandwich in all of the 1970s and 80s? I assume the PB&J. That's when lunch boxes were metal or toxic plastic and the only thing that could withstand the heat of your locker was something as reliable as peanut butter. This peanut butter is so reliable he will join you for lunch and dinner, even if you're having salad.
Jams will vary.
Peanut Butter can either be an ornament or a magnet, you choose!
