I bought this as a graduation gift to myself after university. A gorgeous pen that words can't describe. John's pens are absolutely fantastic - if you're looking to go to the London pen show this October and want to try out a Twiss pen before seeing his table, I have this and another one for you! The other has a titanium nib. This is a slightly larger pen - it is larger (albeit thinner) than my Pelikan M800, but I wouldn't go as far as M1000 size (though I don't have it to compare).
With a blue ink. I found a bunch of random un-labeled ink samples, so it could be anything. It's nice though..!
