TRU REDStaples TR57423 Pen Dry Erase Marker, Ultra Fine Tip, Black

Bought these for a board exam that requires dry erase board/markers instead of paper and pen. They’re fantastic- truly fine tip, 0.5mm, just like writing with a pen. Not sure how long they’ll last but I just need them for 1 day. Wish they had an eraser on the cap. 5 stars anyway for how fine tip they are

Using it on my desk with whiteboard surface, the tip writes fine for maybe one hour of use then falls apart (not completely but it's not a very fine point anymore). The ink also does not last very long, the lines are becoming not ful black very soon. The only good part is that there is no smell and they are easy to clean.

I use these on my desktop glass whiteboard. They work well and seem to last long as I am still on my first one. They write easily and clearly.As with any soft tipped pen I have ever used. If you are in the habit of pushing down hard when you write, the tip will spread.

This was supposedly the finest tipped dry erase marker around. I wanted a bunch of these to dole out with dry erase character laminated cards for players to use in a Role Playing Game for their respective characters. While very fine in width, I found the flow to be somewhat inconsistent which, in turn, varied the width. While I did not return these, I ended up buying another slightly wider width brand that worked very well for my application. Despite the above, this IS the finest width dry erase product I found but just didn't work for me. See my other reviews if you want to know what I liked better.
