Before I bought this sketchbook (in both A5 and A6 size) I did a lot of comparison across the brands available at numerous art supply stores and this is definitely one of the best-priced concertina sketchbooks available out there especially when you factor in size. The concertina format is great for when you want the option to create wide panoramic pictures and I think that it's also a great format for when you want to do a "themed" sketchbook / artist's book.
