Review on 🚗 BOKA 12in Large Student Driver Magnet for Car - Please be Patient New Driver, Vehicle Bumper Magnet for Car Signs, High Reflective Magnetic Sticker for Novice Rookie Driver, Removable & Reusable (3 Pack) by Trevor Blazis

Arrived in a padded envelope and the last 1 inch of the magnet was slightly curved so it won't stick to the car either. But they haven't fallen off yet. Also, my daughter tried putting a magnet on the front of the car (you know, to warn drivers of you or approaching you - teenage logic at its finest) and sure enough, the magnet flew off the car and onto the freeway. . So don't do it. Otherwise they work great.
