The ease of removing the pen while keeping the cap attached to my apron is top notch. The cap also holds the pen tight enough that it hasn't accidentally fallen off during the course of the day (so, no random ink stain).
Now, the point is the best part. I write with it all day long. With the other permanent markers I've tried, the tip gets squishy and broad pretty quickly. This marker is still making crisp lines while being in use for over a week! Making these part of my working uniform.
