Sure, that anchovy and mustard sandwich probably should have been quarantined and sent to the Center For Disease Control, but now you can give people a little warning about what's in there lunch with Crime Scene Sandwich Bags.
Is that roast beef a little too rare? Does that mayonnaise smell a little suspicious? Bag and tag it in the Crime Scene Sandwich Bags. You'll be in an episode of CSI every morning before school. Slather on the mayo and pull off those shades dramatically just like David Caruso as you place the lunch evidence in the Crime Scene Sandwich Bags.
