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

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 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!

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.

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.
