They had gone before I was in primary school, Sen but many desks still had holders for inkwells. There was a std issue ballpoint pen which was fattened at the end where the fingers went (plus in primary, writing on that paper ruled for capitals and small letters).

I did at one point in secondary use a Parker fountain pen that could take cartridges or an ink filler but use the G2 (better known as Parker refill) ball points these days. Favourite is a heavy one I turned on a lathe out of aluminium with brass top and bottom but I do like the long existing Jotters.
