3 Pack - Blue Fine Tip Schmidt 888 Rollerball Refill

Exactly what I needed to get my Rotring pen back in action. It was easy to screw the pen apart, remove the old cartridge, insert the new cartridge, and screw back together. Totally obvious: remove the plastic cap on the end of the ink cartridge before reassembling.Pleasant blue ink. To my eye this gives a medium line rather than a fine line, but I'm pleased. Very smooth action -- something you notice if you do a lot of handwriting.

The ink flows from this pen refill like butter. So smooth, so elegant, so perfect. Revived a trash, expensive pen. Now I have a new favorite pen because of this ink. Love the color choices.

Great replacement for my pen. Delighted that I can continue using it.

Schmidt makes good quality pen refills.

I bought these to replace the ink on a bond and regent rollerball pen that was gifted to me. These refills work great, the roller ball feels smooth and the ink dries quickly and does not smudge or smear. This value is great as well since a pack of these refills cost less than a pack of quality disposable pens. I have not noticed much skipping from these and when they do it is very easily corrected and not a big deal.

These are fantastic! Incredibly smooth, writes very lightly, doesn't glob, and dries instantly.

Exact fit for pen. Will buy again

It was not fit in my pen. The tip is little bigger than old one.
