I've been using these 3x3-inch sticky notes for about a month now - sticking them everywhere from my fridge to my textbooks. The first thing that caught my eye was the vibrant color selection (way prettier than standard office yellows!).

PROS: These are surprisingly good for the price! The pastel colors actually make my handwritten notes MORE readable than darker Post-it® shades. They peel off cleanly without tearing (unlike some bargain brands I've tried). For quick reminders on smooth surfaces like laptops or notebooks, they hold up just fine.

CONS: Don't expect them to stick permanently - after about 2 days on my bathroom mirror, some started curling at the edges. The paper is slightly thinner than premium brands, so fountain pen ink sometimes bleeds through.

BEST USE CASE: I keep different colors for different purposes - pink for urgent tasks on my monitor, blue for grocery lists on the fridge, green for textbook annotations. They're perfect for temporary organization when you need visual reminders but don't require industrial-strength adhesion.

FINAL VERDICT: At this price point, getting 600 colorful notes is a steal. They won't replace heavy-duty Post-its® for long-term projects, but for everyday reminders and adding some cheer to your workspace? Absolutely worth it.
