Post it notes are so handy. Write down a quick reminder, stick it to your desk, fridge, car, wherever. But since they’re just thin strips of paper, any little spill can take them out. Make sure your note can survive the worst with Post-it Extreme Notes, the post-it notes meant for hard living.

These are 3×3” notes that come on pads. You can write on them in pen, pencil, marker, whatever. The backing is made with strong paper and adhesive which makes them tougher than the flimsy paper that you’ll find in most office conditions.

They can stick in both hot and cold environments and will adhere to wet surfaces as well as dry. These were made to live in workshops and areas that are exposed to changes in temperature and moisture. If that describes your office, I’m sorry. You can get these three colors, green, orange, and yellow. A three pack of pads will run you $4.99.
