This is without a doubt the worst ink I have ever used. If I remember correctly I got it for free with my first Lamy 2000.
A pen I lost when my winter coat was stolen in a pub. Funny thing is that I was more upset about the pen than having to walk in 20 minutes in a snow storm without a coat to get home.
This ink was just terrible. The color is black but looks more like you have mixed it with 20% water. Not really greay. It felt very dry to write with it. And the bottle was really cheap, with this weird blot paper roll under it.
I really hated this ink, and ended up throwing it out during a cleanup before a move. And it has kept me from trying any other Lamy inks.
