The Octopus Sheen Ink Bottle – Mermaid is a visual treat! On high-quality paper like Rhodia, it delivers a gorgeous dual-tone sheen that really brings your writing to life—shifting between rich teal and a subtle violet under the right light. It’s definitely a standout for those who enjoy expressive inks.
The ink flows smoothly and behaves well in most of my fountain pens, though it does take a bit longer to dry, especially on coated papers. If you’re left-handed or tend to write quickly, that’s something to keep in mind.
The only caveat is the price. But if you're looking to add something truly special to your collection, it’s worth the splurge.
