Magnetic push pins for stubborn rolled posters

My daughter had a few rolled-up posters that kept springing off the wall — regular poster tack wasn't strong enough to hold the curl flat, and we didn't want to poke pinholes through the posters themselves. These Outus magnetic push pins solved it. You push a pin into the wall, lay the poster over it, then snap the included magnet onto the pin from the front to clamp the poster in place. The magnets are strong, and the only damage is a tiny hole in the wall — not in the poster. — MF
