3M Classic Canary Yellow Post-it Notes
This is the sticky note that started it all. We may have lost Spencer Silver, the inventor of the Post-it Note, earlier this year, but their legacy lives on every time someone reaches for nine square inches of yellow paper to jot down a reminder, a phone number, or an irresponsibly maintained password. 3M churns out so many of these that you can now get 1,200 sticky sheets for just $10, and relieve your brain of the burden of having to remember things.
