Here is an impulse buy novelty item. Mini Crime Scene Tape will give you about an hour or so of entertainment depending on your amusement level. You can CSI everything in your life.
If there were a miniature version of CSI, this is the tape they would use to mark tiny crimes! Use this Mini Crime Scene Tape to repair tiny tears in important legal documents or to mark off the scene of an itty-bitty murder. If someone takes office supplies from your desk or leaves dirty dishes in the sink of the community lunchroom, use the powers of passive-aggression to communicate your perfectly justifiable anger in an indirect, but humorous, way. Each plastic dispenser comes with 100 feet of 3/4″ wide tape, which should be enough even if you run into a mini-serial killer!
