This is definitely my favorite Sharpie product.They are similar to the ultra fine Sharpie, but I like the tip on this one a lot better. I think that it writes more smoothly than the ultra fine, but it's still a thin line so you can write really small.I have lots of these, and still have not had any die or fade.If these weren't permanent it would be my #1 go-to pen. Since it is permanent, it's my #2 go-to pen.
