Pilot Frixion Ball Knock Retractable Erasable Gel Ink Pens,fine Point, - 0.5 mm - Blue Ink- Value Set of 5 & 6 Gel Ink Pen Refill Pack

Not much not to like about them. Cannot even tell you how many I've bought already. I use them for everything (except official documents 😉), and have them everywhere in my house. They are easy to write with and erase. They are like nasa pens compared to the old erasable pens of my childhood (that ripped and smeared more than erased). I'm hooked, and so are most people I introduce these to. I have some motor problems when writing and spelling issues, so being able to make quick easy changes that no one sees once I'm done is fantastic!

Love these pens

My goal was to reduce my 'Post-It Note Footprint.' I now use nothing else! Using these w/Rocketbook products is a perfect combination - BUT I can easily erase & rewrite ANY of my notes on any paper with no (NO) eraser mess (aka, pencils). Recommended by my Canada friend - and am forever thankful!

I have 2 other styles of this fine tip erasable frixon pens in blue ink and I like all of them. I will continue to reorder them again as needed. They have refills available for all of these.This is the first retractable pen in this line that I have purchased. It took some messing with to figure out how it retracts. You push down on the pocket clip. Don't know how that will work out in a pocket. It might extend when not wanted.These pens really do erase and cleanly with no smearing. Frixon pens are now being used to mark on fabric. The marks are easily removed when desired with the application of a heated iron. As the frixon of rubbing the eraser on paper generates heat the ink is removed from paper. Great product but Do Not use on legal or financial signatures.

Rocketbook pens, that will write on regular paper surfaces as well. Can't go wrong for the price.

I use it for practically everything, as the ink does not fade over time. It writes and looks as good as the best writing pens.Black is of course best for filling out and signing documents. With my experience, no one, has ever questioned it as being changed or erasable! Even when I made changes on important documents. The corrected writing simply disappears, leaving no smudge or trace of previous mistake! Then write anything or nothing in it’s place. It is an-undetectable correction.Blue is my favorite over black for routine report and daily writing. It is so 😎 good writing

The .5 is fine and so professional. Looove these pens but they do tend to empty quicker than some pens. Worth it!!

This is a great everyday blue pen with the unique erasable characteristic. The eraser on the end of the pen is not the typical rubber device that uses friction to wear away a layer of paper to remove the ink. The ink itself is reactive to heat -- the "eraser" has a high coefficient of friction so rubbing the inked paper with the erase creates heat and the heat created makes the ink disappear. There is a minor side effect of that reactivity to heat -- if you write with this pen and then set a mug of hot coffee, tea or chocolate on top of that paper, the heat from your mug will make the ink disappear! Same if you use this type of pen to write a note that you put in the window of your vehicle -- the solar-generated heat will make the writing disappear!
