My only M1000 sized pen makes its way back into my rotation. It will joined next month (Edit: released September 2019) by a M1005 Stresemann. In true the M1000 size is too big for my hand but I love the look of these large pens..
The M1000 sized nib is lovely soft springy writing instrument. This particular broad nib is so wet that it is almost too wet.
Yes this ink is green - a very dark green, though it could pass for a black ink if you didn’t look closely. Some small amount of shading and nothing in the way of sheen makes this ink rather mundane in my opinion. It would show better from a more interesting nib.
