From the Moleskine website:
Catering to new trends in expression, the Moleskine Watercolor Notebooks feature a heavy paper, 200 gsm – 25% cotton fiber – cold pressed, identical on both sides, and specially created for Moleskine.
The Moleskine Watercolor Notebooks are bound in cardboard, with a 'moleskine' cover having rounded corners and an elastic enclosure. Each notebook has an expandable inner note holder made of cardboard and cloth.
The first thing I have to say hear is that I have had this watercolor journal for a while and let me tell you that my next project will be to do SOMETHING with the cover.
The paper in this watercolor book is awesome, I can paint on both sides!!
And of course, there is the requisite pocket.
