Parker Vector Stainless Steel Retractable Ballpoint Pen

I bought one of these Parker Vector Stainless Steel Retractable Ballpoint Pens for my dad a couple weeks back, to use as a Christmas stocking stuffer, and liked it so much I ordered another for myself.

When my dad's arrived, I switched out the medium point blue ink Parker refill for a fine point black ink Fisher space pen refill.  I may have another Fisher refill hiding somewhere in a gadget drawer to replace the blue one in mine too. 

I couldn't wait until Christmas, and already gave the new pen to my dad...
