TWSBI Diamond 530

I recently got this pen from the seller twsbipens on eBay, for roughly 43 USD shipped, and it came in a cardboard box with the TWSBI logo, and then a little TWSBI manual, then some layers of foam, then a plastic box that actually held the pen.Inside the box was a small container of silicon grease, and a tool stamped with TWSBI that is used to disassemble the piston mechanism, which is a very new and attractive idea. The pen itself is available in any color you want, as long as its clear, for the time being, and with three nib sizes, extra-fine, fine, and medium, of which I got the extra-fine.

Appearance (9/10)- For only 43 USD, it really looks like a more expensive pen. The barrel is faceted, hence the word “Diamond” in the name, and the cap and blind cap are round. The piston mechanism is visible, and is made almost entirely of plastic, except for a small metal piece, whose function is, for the moment, unknown. The cap screws onto the section, and the section screws onto the barrel. The major significance of this is that because the feed is in a self-contained unit, and that the barrel screws into this unit, there is no chance of ink leaking into the section, which has plagued many other demonstrator pens. Another interesting feature of the section threads is that there is an o-ring on it, which supposedly makes the pen airtight. The cap itself has what appears to be a chrome-plated cap band, which says, in a sort of opaque writing that is quite distinct, says “TWSBI”, and then on the other side, “DIAMOND”, then “530“, and finally, “TAIWAN”. The inner cap is visible, and appears to be a light smoky color. The really interesting part of the cap ring is that it holds in a sort of red resinous material, in which is inlaid a shiny metal version of the TWSBI logo.

Quality (10/10)- For the price, this is a very high quality pen, and it has been said on FPN, that if Pelikan were to sell this pen, it would probably cost 150 USD, if not more. Not only that, but the guys at TWSBI were kind enough to design this pen so that it could be easily repaired, and I do hope that in case of irreversible disaster, TWSBI will offer replacement sections, blind caps, piston mechanisms, feeds, and caps.

Weight and Dimensions (9/10)- This is a large pen, with dimensions at 5 7/16 inches capped, 5 inches uncapped, and although I don’t recommend posting this pen, because it looks silly, and because removing it can actuate the piston mechanism, it is 6 3/4 inches long posted. Although it is a fairly heavy pen, I still feel that it could be heavier for my tastes, and also that the section can be too narrow for my clumsy fingers.

Nib (8/10)- This is a stainless steel nib, and I chose to get the extra-fine option. The nib itself is fairly attractive, despite the fact that I prefer gold -plated nibs. Below the breather hole is the TWSBI logo, and then the word “TWSBI”. On the side of the nib is, in the same opaque lettering as on the cap band, “EF”. The nib also has a sort of floral design on the nib, which I find to be rather attractive, even in monotone steel.

Filling System (9/10)- This pen is a piston filler, and from all appearances, it holds quite a bit of ink, the exact amount being unknown to me. Like the Pelikan, it has the option of filling it with a syringe, by twisting off the section, showing a small hole into the ink reservoir. The earlier forms of the mechanism had a problem with ink leaking past the piston seal, but the new 1.5 version seals prevent that, and I have had no such leakage in my pen.

Cost and Value (10/10)- For the price, this is a very high quality fountain pen, and the only thing I regret about this pen is not getting it earlier. I highly recommend it.

Conclusion (9/10)- I would highly recommend getting this pen immediately, and I may get more of these pens in either the medium or the fine nib size.
