I always keep a pen on my for sketching ideas that come to mind or taking notes, but I have never been able to compel myself to keep a ruler on me at all times. Pen Type-A solves this problem by not forcing me to carry another object. Both are a singular entity until you need to use them and the pen simply unscrews from the cylinder within the ruler. Designed by CW&T is definitely one of those objects that I could justify purchasing because I know I would take it everywhere and use it every single day.
