ParKooRetractable Erasable Gel Pens Clicker, Fine Point 0.7mm, Assorted Color Inks for Drawing Writing, 10-Pack

I’ve been using these as my bible pens for almost two years now. They are absolutely spectacular for my needs, they are vibrant and absolutely a breeze to erase and write over. I love the color selection (I actually purchased a smaller pack originally but needed more variety so purchased this pack and gave my old ones to a friend at Bible study who had been borrowing them because she loved them as well) and they never bleed through the paper and are barely visible on the other side of the thin pages. The tip is fine enough to make precise notes and underlines, and if I make a mistake, it is simple to erase and fix it. I will continue buying them as long as I am able.There are a couple of things to note/take into consideration, and a few things I don’t absolutely love, but that don’t take away from my personal use of the pens:These are friction erasing pens. That means that high temperatures will cause the ink to disappear. Leave your notes out in your car in the hot summer sun and they will not be there when you go to look for them. Same with the pens themselves. If they get too hot, they won’t write properly. This can be fixed by placing the pens in the freezer for a bit to bring the ink back to temperature. Same with notes that were erased by heat. They have to get COLD (like a couple hours in the freezer or rubbed with an ice pack directly cold) but the writing will come back. It’s a pretty fun party trick. The ink erased by the eraser does not come back in the same way though.After a time of not being used, the pens will take some effort to get the ink flowing again. They’ll be patchy and scratchy and I’ll have to gently scribble for a few seconds in multiple different directions to get them writing smoothly again. Not a huge issue, as the scribbles erase cleanly, but if I’m trying to take notes quickly, this is somewhat of a bother.The click of the pens is also pretty loud. I don’t mind it, as the noise is soothing to me, but in the quiet moments of a bible study when there is no other noise and I am furiously scribbling notes in multiple colors, the ‘click’ is very audible and people (lovingly) poke fun at me for it.All in all, these are wonderful pens and I recommend them highly.

I have been using these gel pens for years and I am totaled obsessed with them. They write smoothly and they really do erase when I mess up, decide to write something else, or change my mind. The ink is fast drying with no smears. The pens are a perfect fit in my hand and I love the grib too. The colors are so vibrant and so much fun at the office.

I’m so obsessed with these erasable pens, it’s probably not healthy lol. They write so smooth! Great quality for the price, for sure. Ink flow is better the lighter you write, I’m very heavy handed when writing so there’s times where I may have to go over it again. The ink is super fast drying and doesn’t smear. They work as expected. The pen is the perfect fit in my hand, not too thick or too thin and has a nice grip too. The eraser works a lot better than I thought it would, I’ll admit, I was super skeptical about that. It doesn’t smudge or smear. When you erase something, it’s gone just as if it were a pencil with an eraser. Don’t regret this order one bit!UPDATE: I still LOVE these pens, but the ink runs out FAST. I write a lot for work and it seems these pens run out of ink much quicker than the average pen would.

TL;DR: I think they're still worth the price compared to Frixion, although these have a little less pigmentation in the ink and do not feel as smooth when writing with the pen.I've always used the pilot frixion erasable pens but feel they are pricy and the ink runs out quick, so I decided to try these instead. Compared to frixion, these don't write as opaque or smooth. If you were to draw a straight line, the ParKoo looks a little "stringy" or thin, meaning there will be some translucent areas where the ink pigmentation is not as bold. I also noticed I have to use more pressure or controlto write, as these don't flow across the paper as smoothly. However, they erase just as well and have so many colors! Of all the pens in my pack, the brown pen would not work but everything else works. As a side note, the ink will become "invisible" or disappear under extreme heat, as I learned when my laptop overheated in my bag next to my folder full of notes written with these pens. So heat and/or friction removes the ink it seems. You might not want to use these if your hand written notes are stored in a hot car or near a hot laptop.
