This is a homemade FRISK-shaped laser pointer. You're sure to become a hero if you bring it to school. I take no responsibility for any incidents that may occur from its use, or if it is confiscated by a teacher. The switch may be a bit stiff. A spare battery is included, but it's expired, so you'll need to buy a replacement if necessary. #toy #prank #joke product #magic trick #experiment #FRISK
