DescriptionSpecificationsFrequently Asked Questions (1)
The long awaited retractable version of the popular Pilot FriXion line is here! Pen features the same beloved thermo-sensitive ink that can be erased by friction, but now comes in a sleek, retractable body. Just push the clip to extend and retract the tip. A subtle yellow color appears along the barrel side to show when the pen is extended. The special rubber tip at the end allows you to erase conveniently without having to cap or uncap your pen. The pen writes smoothly and erases without a trace! Refills available for select ink colors and point sizes only.

Interestingly enough, the ink in these pens will actually reappear when the temperature reaches below - 10 C (under 14 Fahrenheit). A freezer is sufficiently cold enough to make the ink start to reappear. It is like a magic pen for adults!

Because the ink in this pen is thermo sensitive, we do not advise for it to be left in hot cars, used for mailing, or subjected to a condition that exposes it to a lot of friction.

Q: My Pilot FriXion pen is not writing well. It seems to be dried out or writing with clear ink. What should I do?
The FriXion ink formula is thermo-sensitive, which causes it to become invisible when heat from friction is applied. If the pen has been exposed to warm temperatures or direct sunlight, this may have caused the ink inside the pen to be "erased." Please try to store the pens in your freezer overnight, then remove them for an hour or two prior to writing to allow them to come back to room temperature. This can usually reactivate the coloring in the ink and allow the pens to write as normal.

Great pen. Higher visibility than I expected, but definitely less than a gel ink or ballpoint would produce. This is a great note-taking pen with no smearing upon erasure that provides a much better set of notes than a pencil ever could. I use this pen for about 5-7 hours at a time with only the occasional ink thinning and have never had a problem described by the other user about "scratching."

Depending on your writing style, this size (0.5mm) or type of ink (water-colorish) might make this pen difficult for you. The scratching requires you to let up on the amount of pressure you put on the pen given the ink is not as a thick as a regular gel pen. Maybe grab a 0.7mm if you have this problem.

Also, if you have a slanted handwriting style like I do (being left handed), the ink doesn't flow as well creating a much lighter line than if you held the pen perpendicular to the paper. I've adjusted my own writing style to work with this pen since I haven't found a better pen for note-taking.

Loving this pen. The ink flows smoothly and I can erase as needed. It's been really great for taking notes that I may want to amend, but that I was to keep clean after I've finished them.
