These markers have a nice fine line which is less than half a millimeter wide, but still easily readable from a distance.

half of these were dried up and not working, a few had the tip mushed so did not produce a fine line but smudged and the last two worked great

Great colors, great fine line

I measured the ULTRA FINE writing lines to be about 1mm wide

Nice clean fine lines

I have not noticed any odor with use, but the lines are very fine, which probably helps

nice thin lines with these

Even if I erase them right away they still leave a line where the markers were.

Some of the fine tips split the very first time I used them so now they don't write in a nice fine line anymore

If you press a little too hard it can blunt the tip a little, for me that is a feature as I wanted a slightly thicker line

I don't know if they changed the formula, but it feels as though these have the most crisp lines and the deepest colors of any of the previous packages I've gotten

Love the fine point and fine line writing for calendar erase boards but some colors don't show up very well.

the fine lines make it easier for them to show their work.

It makes it more fun and less drudgery for some reason, and the line is fine enough that it doesn't make their handwriting sloppy.

excellent leave and clean thin line and have lasted a while now

The lines on sheets are about an inch wide total from base line to top line.

As a homeschooling family, we do a lot of work with small, lined dry erase boards

They really do not smell and they really do have a great fine-line writing tip, with enough colors for everyone in the family to have their own color on the board.

These write like pens and make fine lines and words so much easier to write on dry erase surfaces

I use seven of the colors and like the fine line produced.

Super thin line, and the colors are very vibrant

These markers do write a very fine line however they are incredibly difficult to get off any dry erase surface.

all right...but 2 of the pens were dry on arrival, and for me, they are also a bit too fine lined to be helpful on my calendar

it is difficult to tell the colors apart (especially brown and black) which such fine lines.
