This is a very pleasing little pen, looks clean, modern, and beautiful, and feels very smooth, solid, and high-quality in the hand. You really feel somebody put a lot of thought and even love into its design. It is a screw cap and screw-on to post, which I was afraid would become annoying, but it caps with only about 2 turns and posts securely on the back with a single turn, which is perfect, and gives it excellent balance and length. Because so many people stated that the nib ran to broader "Western" sizes, I bought the extra-fine, but I was surprised to discover that that extra-fine was actually narrower than nearly all my Japanese Pilot nibs, including the extra-fine ones. Only my ultra-fine Pilot Penmanship writes with a thinner line. Maybe my TWSBI is an exception, but I'm quite happy about it. Though fine, it is also wet enough to show off the color of the blue-green ink I put in it and to write very smoothly. The nib does have a slight scratch to it in one direction, which I will have to fix one of these days, but that is minor, and it still feels good on the page. I debated for a long time between the TWSBI Mini Clear model and the Mini "Classic" with black cap and section, finally went for the all-clear, and I'm very happy about that too. They are both nice-looking pens, but there's something I couldn't resist about that very transparent, thick, high-quality plastic, with its diamond facets, and seeing the little nib inside its sturdy chrome-trimmed cap. I still enjoy that, even after having the thing for a couple of months. (There is an inner cap which is visible, but although it has a slight greyish tint it doesn't obscure the sight of the nib. And it works very well; this pen can go many days without being used, get picked up and write instantly without fuss.) I had been a little hesitant to get a TWSBI after hearing of all the cracking problems some of their pens have had, but I have to say I fell in love instantly with this one the moment I picked it up, and haven't regretted it a bit. If it does crack (no problems so far), TWSBI is noted for its quick replacement of parts. So I am enjoying this great little pen without worries.
