If you have something very important to tell someone in your house or office, it’s best to get to the point. Keep it short and sweet then hang it on the fridge or whiteboard with a 3.5” long Ninja Knife Magnet made of ABS plastic. If you happen to find yourself frequently misplacing your keys you can also attach them to the knife with the hole in the end. Don’t touch my leftovers is much more effective when you say it with a knife.
