My first pen was a cartridge pen, then I regressed to a more traditional fountain pen with a bulb, which seemed like more fun
We could use our own pens as an alternative to the school-issue pens, which had a nib, and a long plastic stem, blue in colour. I think kids were allowed to use Biros for most classes by then too, or maybe that came a little later. Once the changes started happening, they happened fast. I kept on using my fountain pen, but by the time I got to secondary school, the inkwells weren't being filled anymore, and many of the desks were like Jer remembers. Someone once told me that one of the reasons some of the old 'technology' hung around so long was that Government contracts were huge. For example Her Majesty's Stationery Office (HMSO) were still issuing ink erasers into the 1960's, because they were available, and folks found them useful as letter openers.
