Now you see it, now you don't! The Uni-Ball Fanthom is the latest erasable gel pen line from Uni Japan. Like the Pilot FriXion, it's thermo-sensitive ink can be erased by heat created from friction! Just rub the rubber area on the cap across the ink to see marks disappear like magic. The special shaped rubber end allows you to erase smaller areas with the tip and larger areas with the broader side. You can erase while the pen has the cap posted on the back, which is an improvement over the Pilot FriXion. You can rewrite over the same surface again and again, without messy residue from correction tapes or white out. Pens come in a nice thin 0.5 mm size.

Ink color disappears when temperature reaches over 60 C (140 Fahrenheit). Interestingly enough, the ink in these pens will actually reappear when the temperature reaches below 0 C (under 32 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!

this pen is ok. there is no grip whatsoever, so writing isnt very comfertable. it does erase, but you have to press down hard and its akward. if you want an erasable pen i reccomend the pilot frixion, they are waaay better

I hate this pen. While it does erase as advertised, I prefer my black ink to look black rather than a faint gray. Will be looking at other brands before I buy this pen again.

i sometimes use this pen to write mostly notes, even though i can write neatly, the ink doesn't really last and tends to fade but it does erase

Great pen...Writes well and feels great in the hand. I will agree that the ink is a bit on the lighter side of black...however I find it perfect. The erasing aspect works as advertised!
I highly recommend.

Nice design and feel, writes very nicely and eraser is very good....but it's definitely not black ink....it's more of a light gray
