The chalk pencils I have bought previously always get dull, and give a wide line; the powdered chalk markers give a nice thin line, but I am not coordinated enough to draw curves well with them

The pens write in vibrant colors, the lines don't bleed into the paper like most pens or sharpies, and erase cleanly this makes them ideal for any graphing or complex calculations.

Very easy to write with, smooth tip, you can write or draw fine lines.

Nice fine line and plenty of colors

Love that a hot iron erases the lines on my quilt projects!

I would like the pens more if they produced a finer line and if the pens didn't run out of ink so quickly.

Nice sharp lines that disappear with the touch of an iron

The only caution is that if, in the process of erasing, the eraser runs over a pencil mark, it will smear the pencil line.

They are great fine line markers that disappear when you iron them

She hit the lines with a hot iron and like magic the line was gone.

Plus if you PRESS HARD the middle of the mark would not show a solid line.

Others will probably love it, as it is a more fine line compared to the retractable

And they do not come off some cloth it leaves a fine white line on your cloth.

The lines are clear and narrow.

The black fine point produces a nice line, with pretty even ink flow

I get much more accurate lines, and use these much more often than the water or air soluble markers, as they are thicker.

I like the fine line it makes and all the colors it

Nice clear lines that vanish when ironed

Really do iron off and you can get a nice fine line where chalk can be so bulky and flakes off.

I am a Pilot fan because of the dense lines they create compared to other companies

The line is fine - good for crosswords; does not bleed.

Comes off of fabric easily, plus you can see the lines to do your work without any troubles

Bottom line, this is my favorite quilt marking pen with many different colors and a thin accurate line.

Erasable ballpoints hang and don't really form a solid line; these operate just like a normal gel pen.

, it cleans the lines pretty much without traces.

The blue fine point produces a nice line, with pretty even ink flow

The pens write in vibrant colors, the lines don't bleed into the paper like most pens or sharpies, and erase cleanly this makes them ideal for any graphing or complex calculations.

They are nice crisp lines that don't smear and they erase completely, leaving NO residue at all.

When ironed off, they left a faint white line

Takes a little bit to get used to because putting too much pressure while writing makes the lines look pale

But, if you miss the line once in awhile, you may see the marking.

They are nice crisp lines that don't smear and they erase completely, leaving NO residue at all.

The fine point is physically a little larger than the ultra fine point, and produces a nice solid line, similar to about a 0.7mm lead, with pretty even ink flow

They make a very smooth line.

There is no smudging eraser lines like you get with normal eraser pens

I was hoping to use in sewing, but the lines are too fine to use for that purpose.

The line is nice and fine, barely noticeable, but just enough so you can follow the line when sewing.
