I was long time in A5, I couldn't deal with smaller sizes. I bought this Malden for a very very silly reason: I love how a personal size Malden looks like. When the new Kingfisher Blue came out I wanted it. Or not, I wanted the Fuchsia first. Then changed my mind :D So I bought the personal size because it looks better than the A5. I have two A5 size Maldens already, I know what I am talking about. I tried to downsize once and failed, now it seems to be working - I might want to stay in this binder so much? I use this I think since June.
