Pilot FriXion Eraser - Gray

I bought 3 of them and they don't work. I have tried them on pens from Jet, even the ones they suggest. They don't work. Doesn't pay to send them back.

I just got my eraser from Jet Pens, and tried it out on one of the standard pens. It erases SO cleanly, and doesn't even leave a faint image behind. I haven't tried it with the markers yet, but it's a good sign so far.

I use frixion to fill out complex legal forms that often need to be modified prior to scanning them and immortalizing their information. Frixion has been a godsend for this purpose, but sometimes I would have to print a new form and start over because of erasure smudges from the pen top erasers. NO MORE! This eraser is amazing - nothing is left behind. It is firmer than the pen top erasure and very cute.

I don't really know why it comes with the black box/frame. The first thing I did was take it out and throw that away. As far as I can tell it serves no purpose.

Handy for erasing large areas of writing/drawing with a frixion pen. However I found this eraser to have a stiffer, more "plasticky" feel than the erasers that come with the pens themselves, which caused it to dent the paper occasionally (even when not pressing too hard.) Still nice to have on hand, especially if you are using the capped version of the frixion pens.
