4 Pack - Schmidt P8126 Short Version at 3.88" Capless Rollerball Refill - Blue

I had a hard time finding refills for my Kaweco Brass Sport pen when I came across this item. I took a chance based on the specs provided however and I’m happy to report it fits the pen perfectly! The ink is nice and bold, writes smoothly, and is exactly the color I was looking for. Highly recommended refill!

These refills are incredibly smooth. No glops of ink ever. The color is very dark blue, not the traditional blue of old. I like these refills a lot.

I bought these for my Montblanc pen since I was having trouble finding blue ink cartridges for it, they did not fit as smoothly as the original due to the diameter of the blue plastic cap at the end of the cartridge. So, I replaced it with the original one and it fitted perfectly. Ink and writing quality are excellent, highly recommended for the quality and value.

Best prices on the refills I could find.

Used in Retro 1951 Tornado. Better than the original ink. Smaller cartridge lasted as expected. Currently use cartridge body with fountain pen ink; works slick without leaking. Fluid writing.

This ink is fantastic. It reminds me of writing with a pencil.

Unless you write slowly and precisely, these refills skip. I use these refills in my Retro 51 Tornado pen and they surprisingly fit a Padrino pen I have. Same problem in both. I am not a speed writer by any means, but I have tried using these while writing in a journal in bed (terrible - they skip, or act like it's running out of ink) and I have used the refills while writing in a journal on a desk. Both pens I use end up skipping. However, when it does work, it works fairly well. I have to slow down my writing in order for the pens to not skip, which is frustrating. I would not purchase these again.

capless, so do not dry out. if you do not put on cap to the pen - smooth writing experience
