And Rob, a physicist and retired civil servant from Hertfordshire, is a real fan of the Platinum Preppy fountain pen.
Seriously. A big fan. He wrote to tell us:
I have collected over the years a huge number of fountain pens (I would be embarrassed to count them) which I use containing many ink types and colours. Most I decided to replace with Platinum Preppys, when I discovered how brilliant and superior they are, and when my non-Preppy’s began to let me down.
So far I have replaced 30 of them with Preppys, and they have never let me down. By my reckoning I still have roughly 50 more inferior and failing pens that I still want to replace (and upgrade) with the vastly superior Platinum Preppys. Or indeed perhaps a few Platinum Plaisirs as well, for good measure and variety, though my preference is for the Preppy because its transparency is an aid to ink management.
…I now regret buying any pen that was not a Preppy, as doing so has been a waste of my money.
