I just finished the book (at last!). A friend of mine told me I would be really like the main character (I did).
As a pen enthusiast, I was really excited when Jake talked about his parker pen (the Jotter, no doubt), but I am really, really interested in the fountan pen he gets as a gift. The book said it was a Waterman pen, and near the end it was revealed to use refills.
Does anyone have any clue about this pen? It may be a silly question for you but i would really like to know.
