I love the design but if I used it as a bag-I'd leave it behind somewhere as I tend to wear cross-body bags. It's too small to put A4 documents in. I suppose I could put passports and travel documents in it but then would only use it once a year! It's too big for a pencil case and I don't really need a pencil case as I have a desk!!!
Why don't they add a detachable handle to it so I can wear it as a bag !!
