Rohrer & Klingner Helianthus Ink

Rohrer & Klingner Helianthus captures the vibrant warmth of sunflowers in a richly saturated golden yellow hue. This is my absolute favorite yellow fountain pen ink. It's bright, and really pops off the page, while still remaining legible (unlike many other yellows).

It has a medium dry time and you'll see quite beautiful orange shading out of medium and broad nibs.

This is dye-based (non-waterproof) ink. It's made in Germany.
