I have been using the stainless steel Parker Jotter ballpoint pen you see here in the photographs as my main pen for over a decade. Those that have been following my exploits would know that I posted about it here.
It does not mean that I am a one pen person. I have others. I have fountain pens too (Lots of them). But I find the ballpoint pen practical for daily use especially when filling up those forms at the banks, where you need to apply some force to make sure the duplicates are legible. So aside from the fact that I dread the fact of losing one of my vintage Parker, Pelikan or MontBlanc pens I like having the very affordable Parker Jotter with me most of the time.
