The Schmidt P8126 is a fantastic rollerball refill, with a smooth flowing and quick drying ink. This refill has a 0.6 mm diameter tip and is sold in a 3-pack of either black or blue ink.

Dried up
My 3 ink cartridges were no good. All three refills were defective.

The Best Company
I have written with pens from MontBlanc to plain Bic Crystal and literally everything in between. I used to think that the best pen was Zebra full stainless. However, this was boring. No color etc. if you want a true honest to goodness pen that is well balanced and writes like a dream, Studio Neat is for you. Hands down, awesome!
