I think this is really fun if you buy it to play a prank on those who are afraid of bugs. They are just your normal sandwich bags except for the picture of a cockroach or some other bugs imprinted on them. So, from a distance, it would appear that a cockroach has invaded your bag and you can bet that the poor unsuspecting soul would be screaming about a bug on your sandwich.
You buy these lunch bags mainly for the fun value of watching people’s reactions to that cockroach. You get a laugh seeing their response, they get a laugh when they find out the truth and everyone is happy. So, get them in anticipation of a few laughs if you have a need for sandwich bags anyway.
