We've probably all seen those silicone pads that promise to keep your smartphone or sunglasses from sliding off your dashboard while driving. But a company called Siconi has one you can adhere to your fridge -- or any vertical surface -- to hold everything from shopping lists to car keys.
The largest of the three available sizes is just $US12, and they should stay sticky forever with an occasional cleaning using mild soap and water. But don't let your mind be limited to only using them in cars and on fridges. Imagine wallpapering a room with these pads, you could hang art, photos, even small children while they're serving a time-out. [Siconi via Fancy]
