Indispensable companion of man, the portfolio crawls everywhere: in our jeans pockets, in our bags, forgotten somewhere in the car, he follows us constantly in our daily lives. Almost considered a self-expansion, the portfolio includes its secrets: ID cards, photos of the better half, money (sometimes…) cards to pay. When it makes the soul, there is always a small mourning to do. That is why we must ask the right questions when it comes time to procure a new one. If we want it to last us several years -or a lifetime-one must go through several steps before making our final choices.
