The pressurised pen
« on: May 29, 2014, 09:01:59 AM »
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.
