The day may not be quite melancholy, but it is raining. When I go out in a bit, my pocket will probably hold one of these two pens, a Pilot Murex with De Atramentis Document Blue ink, or the Sheaffer 3-25 Flat Top with Pilot Blue-Black. Also, not pictured, a Pentel Sharp Kerry mechanical pencil. And in case I need actually to write in the rain, a Fisher bullet style Space Pen in a pants pocket.
Always in my backpack. Waterman 12 1/2 V.S. BABY in mottled red and black hard rubber from 1911-1917 filled with green iron gall ink. Over a hundred years and going. It was made for the French market with 18kt gold rings and 18kt gold nib, because 18kt was the minimum for gold in France at that time.
