EXPO 1871774 Low-Odor Dry Erase Markers Ultra Fine Tip Black 4 Count Pack of 1

I love these. - As other reviewers have mentioned, there is a short break-in period where the line produced by the marker will go from extremely fine to a line thickness that's something like what is produced by a normal Sharpie marker, but I actually prefer the marker once it has broken in. - In terms of longevity, these seem to last for quite a while and consistently produce a bold mark. I use mine quite a bit and a single marker will last weeks with heavy use. Read more

I've noticed that if they are kept upright or not used in a while, they don't write darkly at fist. After writing with them for about 30 seconds however the ink travels back down and they write just fine. They also don't seem to dry out very quickly either which is awesome! Read more

I use these to write on sleeved paper, and on small dry-erase type boards that need writing about standard sized printing. These do not disappoint. I was able to write only slightly bigger than I would with a normal pen, and they wrote very nicely and legibly. I really like using these. I was able to keep the pen cap off for short periods of time and not have the pen get dried out at all while I was thinking about what I was going to write. Additionally, they erase well if you do so fairly promptly (half a day or less). However, as much as I like them, I did have an issue with them. After using them for a handful of days, I noticed the tip of the pen starting to bend ever so slightly. I was using them very gently, and writing softly. Now, after I put the pen away, it seemed to return to the original look after a day. There does not appear to be any difference in the quality of use currently, but it makes me question how long they will last as the pen had the same thing happen the following day after the next use. This will inevitably affect its ability at some point (I use all types of dry-erase pens, and when the tip of the pen starts losing its shape, its performance will be affected). Overall, I liked the pens when I initially used them, but am unsure about how long they will last. However, I will buy again as I have used other pens of this type, and they have not been as nice initially, and they were that good. Read more

I use it for trying out problems during class and for teaching others during study groups. This is a perfect alternative to wasting paper and doing quick calculations. I highly recommend buying this with ultra-fine tip markers! Read more

All four markers were dried out and would not work. I even left them in a vertical position overnight to see if maybe the ink just needed to soak back into the tips, nope still didn't work. The box doesn't look like the new design either so I don't know how old the markers I got are Read more

Great so far! I’ve tried other brands that were very inconsistent & thought that was to be expected with a super fine tip.....NOPE! These are awesome so far! They write smooth & are perfect for small board writing! Def recommend for folks looking for pen-paper like writing on dry erase. Read more

Worked great out of the box. However in a slightly warmer room 2 markers dried out very quickly and just stopped working all together no matter how I tried to get them to start working again. Have not tested the other 2 yet. Read more
