I love my Zenkraft Fantasia de Fleur X-Treme A5 Quadfold Pro. It has my favourite colours in it and is a portable office. It can carry 4 different sizes of notebook (A6, Field Notes, A5 and spiral bound. It also has place for pens and rulers/stencils.
Next week the Swedish Parliament closes for summer recess and my work goes from racing around like a mad thing to mainly being at home and translating. So everything moves from my ring organiser into regular notebooks. Everything from chores I need to do at home over the summer, shopping I want to do in the summer sales, plans for my birthday and work all goes in the same place.
Usually this one is a bit too bulky to carry everywhere with me but over the summer it is perfect.
