Need help with some ideas for a class

[ItalianFX]

I have a liberal studies class called Business & Society.

Our most recent assignment is to find something that can be produced for .02/unit or less. The example he gave us was toothpicks, but we aren't allowed to use toothpicks. I also need to get whatever it is and tape it to my assignment.

I have no idea what costs .02/unit or less. Anyone have any ideas?
