I just returned from downtown Tokyo with my new FP purchase, the Platinum #3776 Century Sai. As an owner of the Shoji, I want to continue the collection of the five lakes around Mt. Fuji as they are released as part of my family's experience living in Japan.
The pen comes in the standard Platinum white box.
Inside, you find the normal pen items: paperwork, two Platinum pigment inks (one blue and one black), and the Platinum converter (in silver). Different from the Shoji box contents is a stamp stating "Written Using Platinum Pigment Ink." Nice marketing idea, but not an item I will end up using at work or in a journal.
The nib is a simply decorated 14k design with a simple #3776 and Platinum "P" engraved on it. Mine is a FM nib.
The pen has a nice heft to it and is easy to hold posted or unposted. I prefer to write with all of my pens unposted. It's obviously a demonstrator style that was a Platinum design decision to "express the profound nature of Lake Sai, the central like in the five lakes around Mount Fuji that is surrounded by a sea of trees and mountains." The cap is the new Platinum "slip and seal" design that is supposed to allow pens to sit with ink in them for up to a year without drying out. I haven't owned one of them long enough to verify this claim, and I usually rotate through all of my pens on a regular basis to prevent ink from sitting that long.
Overall, the writing experience is a nice one that you could expect from Platinum. This is not an expensive Visconti Dreamtouch nib or wet European Pelikan or Onoto writing experience, and I won't try to compare this nib to those different styles of writing. I also won't compare the writing to vintage pens as that opens up far too many comparisons that are too difficult to encompass. Instead, this FM nib lays down a very comfortable line of wet ink. No skips, no hard starts, no scratching. Instead, you have a reliable companion with just the right amount of feedback on fountain pen-compatible paper, and a pen that is ready to write at a moment's notice with an easy, gliding touch that you would expect from one of Japan's big 3. I like the feel and weight of the pen as an all-day writer with a look at the remaining ink through the pen.
My only critique of this pen is that I like the style of the Shoji cap slightly better. Inside the Shoji slip and seal cap is a list of the five lakes surrounding Mount Fuji. Shoji is presented in a reverse font and highlighted in silver. This is a nice touch for the pens designed to be collected in the series. As mentioned above, this was probably a design decision for the Sai, and the simplicity is nice.
One unique item that came with my purchase is the Platinum pen cleaning kit. The salesman talked about the Platinum pigment ink (which I use in my Shoji) and the need for a good rinse every year or so. I like to practice good pen hygiene and keep my pens in use or flushed and dried, but I'll give this a try when the time is right.
