Ballpoint Pen

My problem with ball pens was the width, it was always too thick and looked messy with my handwriting. These days I am lucky to have access to very fine line widths. I use these three regularly. All are Jetstream by Uni. 3 colour 0.38mm, 0.5mm and a black 0.38mm.
 
Out of all of my small pen collection (?), i have a Stainless steel Parker 25 ballpoint which i have had from new from the 1980s (?) which i just love the look of and how it feels to use.
