ParKoo Gel Ink Refills Compatible with FriXion and Friction Erasable Gel Pens, Fine Point 0.7 mm, 7 Colors, Pack of 14

As a left-handed, dyslexic, math teacher turned homeschooling mom... my go to in life has always been the pencil Dixon Ticonderoga--for sure the best. Then I met these gel pen erasables through Frixion first and the Parkoo about 8 month later. Parkoo are cheaper. They have refills in a variety of fun colors and work great in both the Frixion and Parkoo Pens. The ink stands out better than pencil and makes math easier to do than ever before. (Also a big fan of math being done on graphing paper--Mead 5 star graphing notebooks) The variety of colors comes in handy with algebra (changing signs, inverting and multiplying) and geometry. I am always grading papers and colors like orange and pink are less "mean" than red and if I screw up on marking a problem wrong by using the wrong answer key...I can erase and start over. We started using these pens for math and now use them for most of homeschooling. Spelling has really benefited too. Just be careful I have accidentally written a check with these and had to start over. People are not wrong...these last as long as a gel pen, not a standard ink pen. Gel is thicker...basic understanding of volume means it won't write as long as a standard Bic ball point. However, the benefits for homeschooling mean that I am willing to purchase refills for the 5 of us about every other month. Small price to pay for the benefit that we have enjoyed from vibrant, erasable pens. I do feel that the Parkoo refills write smoother than the frixion refills. This also leads to them having a slightly shorter life because the ink runs smoothly until the end without getting scratchy like frixion tend to.

These are a great alternative to purchasing actual Frixion pen refills. I find they erase just as easily and write the same. They also last a while for the price. I like how many colors are available as well, definitely a selling point for someone like me who enjoys having multi-colored notes! Would recommend if you have Frixion pens but don't want to dish out that much money for the refills.

I use Pilot FriXion Clicker pens to do crossword puzzles, and both the pens and refills are expensive if you use them regularly. These refills are a decent value, and they do properly fit my pen, but it appears that there is slightly less ink in each cartridge than the brand-name FriXion refills. (This package says approximately 885 ft total, 14 cartridges.) This ink also doesn’t erase as easily or completely.

I was pleasantly surprised! These are a perfect match for my FRIXION 0.7 erasable pens! I go through pens like crazy, and prefer colored erasable ink. Instead of buying new pens every month or so I can now just buy these replaceable cartridges. I purchased the 14 pack for just a fraction of the cost of new pens. The cartridges fit perfectly in the pen housing. The color is rich and vibrant, and still erases like the FRIXION ink. I'm sold. Will definitely be purchasing again!

These had some negative reviews but I tested my pens and they all work fine. Sometimes they write light but if I shake the pen the ink comes out darker. Overall I really like them.

These work as intended on regular paper, despite running out quickly, which is true for all the brands, and I would say I like the colors on regular paper better than the pilot frixion color options. However, on the rocketbook they don't write as smoothly as the pilot version and they leave a hint of color when you wipe them off to reuse, unlike the pilot version. So if looking to use on paper alone these are great and a slightly better value than the pilot, however, they don't work on the rocketbook, especially with extended use.

I am pretty happy with these refills. I appreciate that the pack includes all of the colors, as the refills for Frixion pens that I have purchased in the past have only been available in packs of one particular color, or sets of three. It seems as if there may be less ink in these refills than in the original Frixion pens, but I still feel that the value is spot on

These are the worst refills I have ever had the misfortune of purchasing. It takes you scribbling to get then started, and not just a little, then once you get the ink to flow they write scratchy, then they stop working again, so you have to start the process over again. The ink comes out faded, gets a little darker, then fades again over and over. Another thing I discovered is when you erase and then right over where you erased, when you come back a week, two weeks later the words are gone. I have added two photos showing the insert completely full with ink and how it fades as you write.

They don’t work. The ink doesn’t comes out sporadically when you’re trying to write. Very frustrating. I threw them out!
