There's nothing like a stuffed Filofax to make this girl with OCD happy. I use the bigger A5 size for work and the smaller personal size for home and personal organization. These agendas are Filofax Metropols, which are my absolute favorite. They're non-leather and durable enough to be dropped and dragged around meetings and in my purse. I am disappointed that there aren't a wide variety of colors for Metropols, but I enjoy the ones I have.
