Having waited for weeks for delivery from Japan via. Amazon (I had gift cards to spend so went there rather than to my usual website) I have finally taken delivery of a lovely Platinum 3776 Century with a Japanese medium (Western fine) nib to use with their Carbon Black ink. I used to use a Jinhao with that ink as it was easy to dismantle and clean; the problem was that the finish was falling off the section, making it uncomfortable to hold, and I was having difficulty getting the flow to stay consistent. It skipped badly, so I re-ground the nib on coarse micromesh and stopped halfway through smoothing to prevent over-polishing, but it never took to the ink well. I'm pleased to report that the ink works beautifully in the pen that was designed to hold it, and, with the promise that it won't dry up in the feed for up to 12 months, it'll be available for addressing envelopes, which is why I bought the ink a year or so ago. With the sale plus two Amazon gift cards, the pen only cost me around £20, plus another £19 or so for Customs fees, and, given that one of those cards was from my aunt who has since passed away, it has an extra, personal significance.
