The Ecosystem Artist Journal in large is the largest journal that I currently own - it measures 7-1/4" by 9-3/4" - this is definitely not a book that you can slip into your pocket.
Here is is next to my large Moleskine sketchbook.
And with my large Webnotebook.
From the Ecosystem website:
the ecosystem life
An ecosystem notebook has a unique past, present and future: The book's past is the various parts made of 100% post-consumer recycled paper, its present is your thoughts and ideas recorded on the pages, and the future is your next step: save the book, or recycle it.
e•co sys•tem art•ist [ek-oh sis-tem ahr-tist]
An individual who utilizes their imagination to produce works that are beautiful and kind to the earth.
creativity is about options
Because you are creative, imaginative, and cherish the freedom to express yourself, each ecosystem artist item features blank paper inside. The 100% post-consumer recycled paper is smooth and perfect for creating your works of art.
Choose a cover format, flexi or hard; choose from our wide variety of colors; and, for a final touch, think about a pocket-insert for added functionality.
Keep in mind that this paper is 100% post-consumer recycled, so it is fairly lightweight. That being said there is substantial show through and even some bleed through with my Sakura Pigma Micron and my Copic Multiliner SP (these pens do not bleed through on higher quality paper).
