Great value for money
The blue-black shade is very professional looking for school notes. It dries reasonably fast on standard paper. Only giving 4 stars because the bottle design makes it slightly hard to fill without a syringe.

Reliable for daily use
I go through a lot of ink at work, and this bottle lasts a long time. The color is consistent from the first drop to the last. Would prefer a wider mouth on the bottle, but otherwise excellent.

Perfect for beginners
This was my first bottled ink purchase. It was easy to use with my converter and didn't make a mess. The black is very dark and legible. Will definitely buy again.

Beautiful Blue-Black
The 555 Blue-Black has a subtle sheen that appears under certain lighting conditions. It doesn't clog my vintage pen at all. Very happy with this purchase.

Smooth flow and rich color
I purchased the Carbon Black (551) and was immediately impressed by how smoothly it flows through my nib. The color is deep and consistent, perfect for daily journaling. No shading issues so far.
