What part of "writes on glass" is not awesome? Any pen that has the word "system" in the name has to be cool. I present the Itoya Finepoint System.
Permanent ink and a .1 point. That to me is sweet music. This pen can go from fine line drawing and doodling to marking up metal. If I owned an awesome meter it would be on 9.5.
If you do not feel like clicking to zoom, the pen says that it is for writing, drawing on clear film, plastic, glass metal and when you write rainbows and unicorns come flying out. (it's true, I tested it.)
Do you have any idea how hard it is to photograph writing on a mirror? Getting my tonsils out when I was 6 was easier and at least I got some ice-cream after that. (I complained and threw a fit so my parents bought the wind up Evil Knievel motorcycle toy) as seen here: Good times.
The experiment went well yesterday. I limited my choices and only took two pens on the road with me, a Pilot Penmanship and a Parker 51. That is traveling in style. Have a great weekend everyone.
