They’re keychains! They’re magnetic! They look like the ends of throwing knives! These $9 refrigerator magnets can send your ‘fridge (or your roommates) a message that you’re not a man to be messed with. And as long as you don’t put them in your pocket with your credit cards, nobody will get hurt.
Nine bucks isn’t an exorbitant price for a bit of clever and cheeky design, but I personally can’t use them on my refrigerator because the dangling shiny keys also make them perfect cat toys. My daughters’ overfed couch dragons would knock them off the door and chase them under the sofa before you could say bansai, and my keys would go missing for days on end.
