Retro 1951 Short Capless Rollerball Ink Refill Fine Tip, Schmidt P8126, P8126 Short Black, 2-Pack Schmidt Capless Roller Ball Refills, fits Retro 51 Tornado Roller Ball Pens.

Very pleased with these refills for my Retro 51 pen. They fit perfectly and write even more smoothly than the original refill that came with the pen. I ordered the black fine-point rollerball refill and will definitely reorder when I run out.

Consistent quality, writes well

Not as dark as I would have liked but seems to work well.

Same as the original pen cartridge; smooth writing with no broken ink lines. Packed and sealed well.

It fit my Retro 1951 nicely. The "fine" is not really fine. I'd like an extra fine option. The cartridge works fine but does skip and smear more than I would expect from a high end pen (I understand the refill is not the original). After a week of using this at work, I have gone back to my old disposable pens for most tasks and only use this in meetings where I take my portfolio (which is where I keep the pen).

Writes great and good value. Pleased with the refills.

Very nice seller with quality product who delivers on time.

Works well

Bought these refils for an Acme pen, and they worked perfrctly.
