Quartet Dry Erase Markers, EnduraGlide, Fine Tip, BOLD COLOR, Black, 12 Pack (5001-13M)

I bought these because I use a whiteboard to take notes with my job so I don't have to worry about shredding personal information when the call is over. They're doing fine so far.Pros:-They write well. Even when the ink is low, you can generally write on sides of the tip pretty clearly until it's completely out.-The clear sides to see the ink level is phenomenal.-They aren't terribly expensive (at least from what was available when I bought a box).-If you set it down gently, the cap will usually prevent it from rolling away.Cons:-If you don't set it down gently, the cap doesn't do much to prevent rolling away,-The cap doesn't stay on the back of the pen very well at all. It comes off pretty easily if you set the pen down cap first, and if you drop the pen at all (which I'm prone to doing, or happens when you don't set it down gently enough and it rolls off the desk) it pops off and ends up goodness-knows-where.-I'm going through a pen every one to two weeks, though I don't know if that's normal for as much as I use them. I do eight hours + a day of note-taking with them, and didn't try another brand prior to this, so it could be perfectly normal. It's still worth four stars!

The ink/color writes well on the glass white board - bold, distinct - but I wanted fine "nibs" so I could write more clearly on a small white board and they do not work well for that purpose. I would not call these "fine".These pens would be good for a big white board that is viewed from a distance but not for smaller more personalized desktop white boards.

I use these everyday!! They write clearly and i can fit a lot of info in a small space using them. But the last batch I purchased is having some difficulties. Its like the point material is solid and the fluid can't get through, I wouldn't have mentioned it but so far a quarter of the box is no good.

Don't clean off as well as I had hoped, even on a Quartet board.

This is the only brand I will use on film slates. Others I've t won't erase clean. These do.
