Faber-Castell 185506 Standard Ink Cartridges Standard Black

It's good ink. Don't get it wet.

These refills are great for fountain pens. They click on the the pen tap and the ink writes very smoothly.

I would 100% recommend this product, but you should still look for alternatives. I bought these cartridges for my faber castell pen, and they were fine. The ink flowed very well, and the writing was very smooth. I thought that it was a good deal too, since you do get a good amount of ink for a relatively low price. Even better, there are no leaks, and it is very easy to just push them into the part of the fountain pen that receives the cartridge. However, I've been looking into the faber-castell website, and discovered they had so many more colors, and cool ones at that. So yes, buying these would be a solid purchase, but why would you buy this boring blue, when you could buy some other exotic color for the same price?

Great and do not leak

Works perfectly. I like black ink.

The cartridges are good however, the box the cartridges came in, was open and 2 cartridges missing.

Let's honest, it is just ink. Now as a fan of ink and all things pen related I will say that this is great ink, in a form factor that is a perfect fit for the pen. Beyond that, not going to change your life.

Ink flows just fine. Luv the color
