I like multi pens because they allow me to have different options within just one piece or item — 2, 3, 4 colors and/or mechanical pencil included—. I work a lot on field and offices moving from one place to another, many times signing documents and or reviewing/modifying plans, layouts or different drawings so it’s a lot easier for me if there are less separated items to carry. I have owned different models of Parker, Rotring and Cross multi pens. Please share your thoughts to learn from each other on current multi pens options, pros and cons, preferences, prices, etc. Please add pics if you wish.
