Even if I use it for a long time, the line doesn't become dull.

Each of these highlighters made clear sharp lines, and did not bleed through the paper.

Definitely the brightest, sharpest lines, and I love that I can see when I've run out of ink.

These are my favorite highlights as they remain bright until the last drop of ink (which you can see when it's getting low) and they make clean crisp lines when used to either highlight with the wide tip or underline with a thin line

An incredibly smooth line and great color.

My only complaint is they could only be found in the finer line I would like to have ones that had a larger chisel tip.

Nice bright line for highlighting.
