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.

This pen ink is completely...
May 29, 2012

This pen ink is completely erasable. (Well, there is a very very faint trace of what you've erased, but that's only if you know what was there and are looking for it intently.)

I do agree that the ink is not a true black compared to other gel ink pens, but it's black compared to other ballpoint pens, in my opinion.

My only problem is that I don't know where to use this pen except for fun.
I've heard of people's notes disappearing after leaving their notebook in a hot car for hours, or writing disappearing from when the papers rub against each other for extended amounts of time. Therefore, I wouldn't want to use it for taking notes (don't want all my hard work going down the drain) or on anything I turn into my professors (how troublesome it'd be if they threw away a seemingly blank piece of paper and then give you a 0 for your "missing" assignment/test).

Unless you live in a climate that's perpetually cold and have nothing to worry fear regarding the "accidental erasing," this is a good novelty item, but that's about it.

The ink is the same as any other Pilot FriXion pen - so it's already considered great for erasable inks. This pen differs in the external presentation - and I have to say it's incredible.

The body is thick for a perfect firm grasp with a grip which has just enough traction, the eraser is located at the tip for easy access and the clip just gives you another excuse to carry it around with you everywhere. And there's just that sense of style.

A definite recommend!

Nice design. Comfortable. Writes well. Not your typical ink. Ink is kind of watercolor like and light but it writes VERY well.

Wow, I liked the original FriXion, but this one is great. Easy to carry in the pocket and click with one hand to write, and the eraser is right there without having to remove cap. The ink is not as dark as I would like, but dark enough to work good. Erases completely and the refill is the same as for the original FriXion with removable cap. Next we need a "high class" version of the retractable FriXion. As usual, great service from JetPens - Thank you so much!

I like this pen but it...
August 4, 2015

I like this pen but it caused me a lot of trouble. Don't get me wrong this pen is excellent, it writes well and it erases better than any other erasable pen I've tried. The only thing I don't like is the ink is more of a watery gray instead of a dark black.

Now the trouble part:

One lovely rainy morning on the way to class everything in my backpack ended up getting soaked, had to sit through a four hour class, etc. and when I got home my agenda was still wet so I got out the hair dryer. Unfortunately I saw the ink disappear as I moved the hair dryer to dry the pages. I should've thought about it ahead of time, but I didn't know how else to dry a sopping planner. Even though the ink was gone I could still see traces of where I had written on the pages, so afterwards I had to go and recopy everything with a different pen.

My advice is to not use this pen for important things because you never know what will happen. I'd rather not waste time trying to recopy what has disappeared, or risk it happening to an assignment. I really don't know what else to use this pen for now, so it hasn't been used since that accident. It really is a cool novelty though, so if you've got a use for an erasable pen by all means get this one, it really is the best I've found. Just don't apply heat to the ink.
