I filled the Platinum Carbon Desk Pen with Platinum Carbon Black ink (in a cartridge) back on January 26th. InCoWriMo was about to begin and I figured the waterproof ink would be perfect for addressing envelopes and postcards. As it turned out, I used this pen for nearly all my postcards. Only the first few were written with another pen/ink combo. Without knowing any better I picked coated postcards and only this pen/ink combination really worked on them. I did need to clean the nib occasionally as the coating accumulated on it.
The nib is a “superfine” although I’m pretty sure this is the same as the “extra fine” nib I also see offered. The nib is similar to my other Japanese extra fine nibs and a bit wider than some, such as my Sailor extra fine.
It’s a thin and light fountain pen, which isn’t normally to my liking. I use this pen for short writing sessions – a postcard, an envelope address, or a quick note. I have the desk stand (which costs more than this sub-$15 fountain pen) so the pen is always available for a quick note. I’ve come to appreciate having a pen on my desk that’s ready to “grab and go”, no uncapping needed.
The ink is a pigment based ink and the feed in this pen has slightly wider channels to account for the particles in the ink. Five months is probably a little long to keep this type of ink in the pen. But, I didn’t have any hard starts or skipping so I didn’t see the need for an early flushing. The pen was used frequently in February, it was used less frequently after that but still a couple times a week. The ink was easy enough to clean from the pen, but it did take a little longer than I expected. I suspect the ink had dried a bit in the feed and was coming loose as I flushed the pen.
The Platinum Carbon Desk Pen with Platinum Carbon Black ink was due for a bath by the time I wrote it dry. After it was refreshed I popped in another cartridge and the pen is back in its place on my desk.
