This pen fits comfortably in your hand, I have him always. Sign at the checkout for card payment cash on thin paper and corrugated sheet: Absolutely no problem. Receive packets at the door when it is raining, Klembrett and paper soaked in: Who cares? Also to make extremely practical when geocaching, outdoors notes or crossword puzzles in the subway. I've already written exam at the university completely written with this pen. Lines are not interrupted, even sketch goes wonderfully out of hand and you do not feel well after two hours, already getting pressure points on the fingers as with other coolies. The compressed-air technology behind it is as simple as it is ingenious. Marking out drill holes on walls and ceilings, to wallpaper or plaster board, Go. Cutting lines to laminate for the saw stand: Wonderful. It is simple and can be used without restriction for all. Just really great buy recommendation!
Next I like to try him under water. ^^
