12 Blue Erasable Gel Pen Refills, Gel Ink Refills Compatible with Erasable Pens, Fine Point 0.7 mm, Perfect for Writing Planner & Crossword Puzzles

At first i was disappointed because of the scratchy failure to ink my paper. The wax they use to seal the tip is red so I guess I thought that was supposed to be their ink. It does take a vigorous picking off. I've picked a tip right out of a brand new refill because of the effort required. Maybe it was extra tough for some reason like summer temperatures.They do produce a decent red stream if you move gingerly but start out a bit pink and dry out during long quick strokes. This happens with Frixion too but these are less expensive. Erasable ink is a little different than normal ink and I think it is a challenge for engineers to get it working. For example the ink is thick and cartridges don't last long. I have these refills in my Frixion side click and maybe a shim would have them stick out a bit more? They function fine compared to Frixion as they erase well and leave a legible mark.

I love the Frixion Erasble pen. I do a lot in blue ink. I cannot ever find the pens in blue at the store. These are a great replacement insert. Fits the pen and writes well.

They’re a bit longer than expected for the pen shells I own, yet I managed to clip a few millimeters out of these to make them fit my pens and they work just fine.

The ink didn’t flow as well nor do they last as long as the original samples.

This pen writes very lightly, more of a mid-grey than a black ink.

They seem to work ok.

Great value

I found these on Amazon recently and so far I am pleased. They write smoothly and erase as well as the name brand refills. The name brand refills get used up quickly. I hope these last longer.
