Three pen set includes colors: black, blue, and red.

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.

Note: this Ball Knock pen is the Japanese version of the Pilot FriXion Ball Clicker US Gel Pen, and differs in body style from the Ball Clicker. The Ball Knock Light Blue and Blue Black ink colors are the same as the Ball Clicker Turquoise and Navy ink colors, respectively.

These have become my favorite workhorse pens for classes, and the 3-color set is a very handy for corrections and general writing needs. The U.S. version is slightly cheaper, but has a printed design that I'm not fond of, so I opted for the Japanese set.

These can be twisted open for refills which makes them relatively economical, however the ink gets used up quickly due to being slightly thick. Using the 0.7mm tip also causes the ink to be used up faster, but it creates a smoother and more pleasant writing experience.

The eraser is not like a typical pencil eraser that gets used up quickly, instead it is a hard rubber that shows very little wear even after a lot of use - but it still works great!

The ink color is relatively light compared to gel pens such as the G2 or Signo, but it's still perfectly acceptable in my opinion.

I prefer the retractable style after trying the capped version for a while, since you don't cover the eraser when posting the cap. However the retractable cartridge doesn't fit quite as snug as the capped style, so there is a very slight jiggling feeling to the pen during writing, whereas the capped version is very solid-feeling.

The little plastic "wallet" that they come in isn't anything special, but it's nice for staying organized.

This is my first time using Pilot's erasable gel pens, and I'm quite satisfied with the results, although the ink has a slight watery look to it, it still writes smoothly nonetheless. The erasablity part however, does erase quite well, but there is still a faint, slightly yellowish tinge, left over from what you've previously written, especially on thinner or low quality paper. On thicker paper, it erases well but still leaves a slight imprint (like if you wrote something hard with a pencil and erased it with an eraser). You can't have the best of both worlds, and I'd still prefer to have an erasable pen to one that's not.
