The pressurised pen

[?eter]

So I know there are three size variants and 2 colour variants of the standard pen. The literature all refers to it as a 'pressurised' pen and I had this idea in my head that they're made by Fisher, but does anyone know who actually makes them or anything more about the technology? I've done some searches here and not come up with anything.

OK, I know of the 58mm, 91mm and 70 something variant for the SwissCard. But color variants are new to me.

I highly doubt it's made by Fisher. Yes, they did it first but you can get them from different manufacturers nowadays. For instance some Parker refills are pressurized.

@enki,
The standard is blue, but the ink cartridges that come in the replacement parts kit are black. At least the ones for the 58mm.
I prefer black and have order some through this ebayer.

Thanks for the info. All of mine are blue. It's also the standard color used in Europe for all regular pens as well. I read somewhere that in US it's black.
