This is a Hong Dian fountain pen. I bought it because I liked the color, but I ended up with too many pens and never used it. - Color: Blue - Nib Material: Stainless Steel - Mechanism: Cartridge - Design: Gloss finish I did a test write with blue ink once, and then cleaned it. Please be aware of this. The nib is equivalent to a Japanese F, and I believe the ink flow is good.
