ParKoo Retractable Erasable Gel Pens Clicker, Fine Point, Black, 6-Pack

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.

Works great

Love these if I make a mistake I can erase

The pens do work and are erasable similar to Frixon clicker pens. Have to write with the pens a little be to get them to work. Ink does not flow as smoothly as Frixon pens.

I couldn't believe that these actually erase--and really well at that. The ink dries pretty fast and these pens are wonderful for writing my class notes. They're also super juicy and smooth to write with. The listing warns about the ink here being heat sensitive and they mean it. Definitely wouldn't use these on any important documents and the ink totally disappeared when I tried to use these to label a piece of masking tape on the bottom of a warm petri plate in the laboratory.
