I have been purchasing Moleskine Watercolor Books for many years now, however I found the size a bit limiting.  When I saw this item for sale, I thought they had made it with me in mind.  I paint large, so a small sketchbook limits my exploration for large pieces.  This A3 size is just right.  The paper is the same, it is exceptionally sturdy as all Moleskines and the very roomy pocket makes it nice for storing other artwork flat.  I loved this so much I also purchased the A3 size pockets which are great for flat storing smaller paper works!  Do yourself a favor, take the hit and give this sketchbook a try.  Even if you do not work in watercolors, it works great for other mediums...I use ink and acrylics.  Additionally, if you are an art journaler, this is the book for you!
