Pilot Parallel Mixable Colour Blue-Black - Ink Cartridges

Pilot Parallel Mixable Blue-Black ink cartridges

I like the ease of using cartridges when I do plein air sketching.

First fountain pen!!

Love it, writes beautifully. Perfect starter pen. Unfortunately I now want more fountain pens.

Customer service

The cartridges are fine. No issues. I do want to point out the great on-line customer service you guys have. Its great.
