PILOT Extra Fine Point Permanent Markers, Blue Ink, 12-Pack (44103)

In the search for the perfect pen for clear Sticky notes, I found these and they are exactly what I’ve been looking for. They only take a few seconds to dry on the sticky notes, then never smear. If you’re looking for the perfect pen for annotating on clear sticky notes, these are the pens for you.

These have become by favorite pens. I carry one around with me wherever I go.

I work in a sign-art department where accuracy and ink performance are everything. These pens have very saturated pigment and write on every material - plastic , metal, fine paper, etc. and the ink doesn’t fade under LED lighting.

Durable and inky! The tips hold up well and it last as long as I expected.

I paint rocks and was looking for a good black fine liner pen. I tried these Pilot pens, put the ink to the fade test in the sun for several days and the color held up, unlike the other name brand pens I also tried. I am happy with these and will buy them again at another time, if I use these all up. I recommend them if what you are writing on is subjected to sunlight.

I really wanted to like this but it bleeds. I only used it on Arches watercolor for a painting and the lines are not sharp it feathers and lines not sharp

You can't go wrong with these marking pens. They work very well on glass slides. One problem I've had with similar pens from other brands is air-drying; by the time the pen is brought into the field of view, it is already too dry to write on a slick surface like glass. This isn't an issue with these marking pens, they are quite reliable.They make great gifts for pathology residents, by the way.

I use it to write on film photographic prints. It has a very sharp point and writes on anything. Won’t rub off. Can be removed with certain solvents like Pec 12.
