A portfolio or writing case is the most compact business accessory for keeping writing utensils, your mobile phone and a tablet PC. Classic writing cases have a slim shape and contain a note pad. This variation is especially practical for conferences because you have everything important at hand. In contrast to that a document folder reminds in a very slim kind of briefcase where you can leave some files and a thin notebook. Made of genuine leather a portfolio is a very elegant accessory that discretely underlines your sense for details in every meeting.
