ParKoo Retractable Erasable Gel Pens Clicker, Fine Point, Make Mistake Disappear, Black Ink for Note Taking and Crossword Puzzles, 6-Pack

PARKOO is **absolutely** the way to go in erasable pens! I buy the color packs but get additional packs of BLUE often and regularly. It is the MOST VIBRANT and BEAUTIFUL BLUE I've seen in *any* pen, and these erase so cleanly! Additional details: • Quality of Erasures: As a high school math teacher, I grade countless papers. Using non-erasable pens was annoying because in my haste, I’d comment/deduct points only to realize the student wrote the correct answer in a weird place. Scribbling out is messy, and "Wite-Out" is obvious and tacky. ParKoo erases so cleanly that you see nothing but the blank paper – crazy! • Ink flow: There's a little plastic thing covering the ball point until you're ready to use the pen, keeping the ink fresh and flowing. I avoid removing those and letting pens sit forever unused because the flow can become thin and choppy, or they simply dry up. • Reversibility: I used to worry that students might erase my deductions/comments when papers were returned and claim an incorrect calculation of their score. If that were to happen, I can put the paper in the freezer and the ink will REAPPEAR!! I’ve never had to do that, but it's way cool (literally)!! • About the photos: o You can see the vibrant color when compared to a regular blue and how it erases even on graph paper which is highly absorbent. o It stands out on colored paper (not so important, but cool nonetheless)! o I included two pics of a test I graded. I was going to add a graph to further explain a concept but decided against it. You can compare the before & after results. o The close-up of the pen shows the little plastic thing that keeps the ink fresh until you’re ready to use it. o Then there are the freezer shots! I put the erased graph paper sample in the freezer for about 10 minutes. When I took it out, not only can you see the ink reappear, but even the happy face I’d initially drawn in the “O” of PARKOO. I’d erased it because it looked dumb, but the freezer sees ALL! :D I don’t typically write marathon reviews, but this product deserves the time and effort expended to explain PARKOO’s superior quality! Try them out – I think you’ll love them!

The eraser is smoother than the usual erasers you get on an erasable pen ( as with the Frixion pens). It is gentler to the paper than the other kind. Pentel Frixion has a similar eraser on their 0.5 pens (looks the same) but it’s not as soft: it stretches the paper and roughens up the paper surface. The ink is brighter (at least the blue colored one) and lasts just as long as the Frixion pens. To those reviewers who comment on how the ink is not really erasable or that the pens stop writing too soon: First of all these are erasable pens, so all expectations that they will last as much as regular pens are misplaced. Their benefit is you can erase them and that comes with some inherent drawbacks, mainly that the erasable ink is more fluid than a gel or regular ink (it’ll get used quicker) and that the ink indeed does not erase 100% (90% is still pretty good). The type of paper you use is important. The pens will work best on very smooth paper: I.e. these pens don’t like porous or non-smooth paper because the ink won’t stay on the surface and therefore won’t be easily erased. Printer paper won’t work. Drawing or sketching paper also won’t work. You have to really look for this kind of paper because it’s rather uncommon. Amazon sells some- not cheap. Daiso Japan (west coast US or online store) does too: more affordable. The typical three hole filler paper is smoother than printer paper, but unless you invest in thicker filler paper you will likely either tear or stretch the paper at the spot your are erasing. Still not smooth enough. If you want to erase some pen markings, wait till the ink dries first (a few seconds) before you rub the ink off. Otherwise you’ll be spreading the ink through the surface of the paper and therefore making it less erasable. When you do erase, sweep off all remaining particles: they’re not visible but if you touch the paper, you’ll feel them. If you don’t sweep those off, and write over a seemingly clean spot, you will gunk up the tip of the pen and after a few times, it’ll stop working. If the pen stops working, don’t shake it: you’ll waste ink. Instead keep doodling on clean -smooth-paper until it does work. When switching back and forth between these pens and pencils (e.g. HB) you might end up accidentally running the pen eraser over pencil markings. If that happens, you’re out of luck because the only way to remove the pencil smudge is to cut that piece of paper off. The pens will write over pencil and vice versa. But if you want to erase this mix, use the pencil eraser first (high density polymer eraser) and then use the pen eraser. If you write in a notebook (like a spiral notebook for school), and you are not kind to it (i.e. messy) you will end up having your pages all rubbing against each other all the time: you’ll effectively rub off some of the ink. It’s best to use these pens on loose paper and preferably only on one side of the sheet. Even with all of these peculiarities, I love these pens. They are good at what they do. But they’re not for everyone. More about these pens than you’ll ever want to know. At least now the info is complete. Not OCD at all - not me.

I am really impressed with the erasable pen! The functionality of being able to correct writing errors so easily is incredible. The special ink allows for erasing without leaving any residue or smudges, which is perfect for those who like to keep their notes clean and organized. The design of the pen is ergonomic and comfortable to hold, allowing for smooth and precise writing. Additionally, it comes in various vibrant colors, adding a fun touch to daily use. Another positive point is the durability of the ink. Even with frequent use of the erasing function, the pen continues to write perfectly, without any skips or interruptions in the ink flow. I recommend this pen for students, professionals, or anyone who values practicality and organization in their notes. It is an innovative product that truly makes a difference in everyday life! ---

It works well enough. Sometimes the ink gets globbed up and if you try to write over something you erased if has some troubles. But by far the best eraser for ink I've ever used. It's almost like it was never there. That makes me happy because my job requires erasable pens and boy do I erase a lot. For the price it can't be beat.

Great pens, i buy more every time I run out. They don’t last too long if you write a lot but the quality and easy erasing makes it worth it.

I only use these pens! Only thing I don’t like is that it runs out of ink quick lol but I keep buying them because i love how I write

I really loved these pens. I have to write on documents that, if you mess up, it voids the whole document. These pens helped because I could mess up, erase it, and rewrite and nobody ever knew the difference. But, after a few months of using these I've found a flaw. Once you write, after a couple of weeks the ink just wears off and goes away. So essentially everything you wrote just disappears like disappearing ink. I have had documents returned to me because the recipient went to use it and the writing is completely gone. So my suggestion is, if you're writing on something important and the ink disappearing is going to be an issue for you, don't use these. I hate to say that because I love the pens otherwise....but I just wanted to warn others.

I bought these erasable pens about six months ago and liked them immediately. Today as I'm using my pen I made a mistake on paper. Thinking what a pain it is to start all over again, I remembered that these aren't regular pens. There erasable! How could I have forgotten. That is what I was so impressed with a while ago when I first bought them. The eraser gives a clean erase, for the most part. Clean enough to come here and let you know how fantastic these pens are. They write good too. I have the blue ones, and will probably purchase the black ones. One more thing: You have to use the eraser on top of the pen. Your writing won't erase with a regular eraser. I think that's a really great feature. You have the attributes of a traditional pen and an erasable pen. Permanent but not permanent.

I don’t recommend the ink runs out some of them don’t have any ink at all or the ink is dried up.
