Pelikan Super-Pirat Royal Blue/Ink Eradicator Pen, Fine Tip on Pen, Broad Tip on Eradicator, 2 Pack (921734), 5.000

These pens are FANTASTIC and work great! They keep my handwritten letters looking neat and professional. :o)The downside is there are very few inks that these will work with; stick with the "washable" blues: Pelikan Royal 4001; Lamy Blue; Sheaffer Blue; Quink Blue and Waterman Serenity Blue. I've tested all of these and they all work.They will NOT work with dark blues, turquoises, black, etc.

Works *ONLY* for Pelikan 4001 Royal Blue, bottle ink or cartridges.Does NOT WORK FOR ANY OTHER COLOR in the Pelikan line.May not work for any other brand of blue ink; it's hit or miss.The eradicator works be chemically changing the blue dye so it becomes transparent. Works with other vendors *IF* they use the same blue dye *AND* don't add any other dyes. Vendors don't state the ingredients for their inks, so it's hit or miss of whether this will work for non-Pelikan brands of blue ink.

Sellers description is completely wrong. Eradicator does not work as described, it smears the blue ink when attempting to remove it, and it also damages the paper. It is useless!

These work really well with the pelikan blue ink. Which comes either in cartridges or bottle. The clean up end doesn't soak the paper too bad, though you still have to wait 15-20 seconds for it to dry before rewriting.The only down side is that you can't rewrite over the cleared area with the fountain pen again. You have to use the ink on the flip side of this fluid eraser. The writing tip is a bit like a thin marker. The ink looks a bit different than the fountain pen ink but it isn't annoyingly stand-outish.I haven't used them long enough to be able to know how long they last yet, and since I am quite used to writing with ink pens I don't have a great number of occasions to use these. I don't know if they will dry out from non-use yet.I really like them though, the option to neatly and cleanly eradicate my penmanship mistakes is wonderful.

I teach my kids still to write with ink pens and these erasers are a must have in our learning journey. The erase mistakes and write over easily. We used to buy them in Germany and I am glad finally found them in the US. One lasts about 3-4 months and I always stock up. Its a school supply we will never go with.

Didn't work too well.

Works great!

This only works with royal blue ink, guys LOL. I used them back in Germany in school 9 years ago, and they still work exactly as I remember! It never ceases to amaze me as it washes away the blue so rapidly (I know it just makes it transparent but alas).
