Commemorative edition worth it

The packaging is lovely, making it a great gift. The ink itself performs flawlessly in my medium-nib pens. No clogging issues after a month of use.

Great for students

Very reliable ink for school notes. It dries reasonably fast on standard notebook paper with minimal feathering. The only reason I didn't give 5 stars is that the bottle design is a bit tricky to fill with small converters.

Beautiful scent and smooth flow

I bought this for my daily journaling. The black is deep and rich, not gray like some cheaper inks. The subtle floral scent makes writing feel like a luxury experience without being overwhelming.

Perfect non-carbon black

I needed an ink that wouldn't stain my hands or clothes if I got messy, and this non-carbon formula is perfect. It cleans up easily with water but stays permanent enough for records once dry.

Smooth writer

Very consistent flow. I use it in a fine nib pen for math equations and it doesn't blob. The shade of black is neutral, leaning slightly cool.

Good but scent fades quickly

The ink writes well and the color is solid. However, I was hoping the scent would last longer on the page. It disappears almost immediately after application. Still a decent product for the price.

5 FAQ

Q: Is this ink waterproof?

A: No, this is a non-carbon dye-based ink, so it is not waterproof. It will smear or wash away if exposed to water after drying.

Q: What is the shelf life of this ink once opened?

A: If stored in a cool, dark place with the cap tightly sealed, the ink should remain usable for several years. If you notice sediment or a change in smell, please discontinue use.

Q: Does the scent linger on the paper after drying?

A: The scent is designed to be noticeable while writing to enhance the experience, but it typically dissipates shortly after the ink dries on the page.

Q: Is this ink safe to use in vintage fountain pens?

A: Yes, as a non-carbon dye-based ink, it is generally safe for vintage pens provided they are cleaned regularly. However, we always recommend testing in a less valuable pen first.

Q: Can I mix this with other Ostrich ink colors?

A: While technically possible since they are dye-based, we do not recommend mixing different colors or series as it may alter the chemical balance and affect flow or color integrity.
