Pros:
- Nice, bright colors
- Cute pen design
- No bleeding through paper

Cons:
- Have to be careful with light-upon-dark colors; colors will mix

Overall: I was a little discouraged by the long wait for them to come in, but it was worth it! I wanted these to take really cute notes, or even for draw/sketching. The only downside was the 0.4 mm side for the light blue pen being a little dried out, so I had to be careful with that. But other than that, great purchase ! :-)
