Cons: As you know, if you accidentally write on a surface by mistake, it's tough to clean off
• Sharpie pens are one of the greatest inventions ever made. They're reliable, consistent and really do the job well. When I say that, I'm referring to the Super Sharpie Twin Tip and standard Sharpie markers. I can't say the same for the ultra fine or Magnum. Both of those seem to dry out faster. I used the magnum on my moving boxes. It didn't write as clearly as I'd like, and ran out of ink faster than expected. The ultra fine models have a nice, clean line but seem to run out of ink quickly, too. For most uses, I'll stick with my favorites: Super Sharpie Twin Tip and standard!
