I do have some ‘proper’ pens though and these I have had for many years. Of them I have used the Montblanc Meisterstück and the blue and gold Waterman Carene ballpoint pen the most. Given my problem with pens and pencils it is surprising that I have never lost them.
Ink-wise I use Montblanc and Pilot Iroshizuku the most. I tend towards blue-black and blue-grey colours.
