The only thing that dismayed me a little is that (I think) because of the little accordion pocket in the back, the covers tend to warp a wee bit

and I plan on traveling a fair bit during the next few years.

The watercolor paper tends to warp a little bit if you over saturate the paper-

The paper has a bit of teeth but when you add water, the inktense colors smooth out and you can't tell that the paper is not perfectly smooth

They are flat now, but are a bit thin: Thin enough that as I live in a clime with ferocious summer humidity, I worry a bit about future warpage

(the page will curl a bit, but will lay flat after it's dry)

The paper can warp a bit if you're doing really heavy handed washes

That did`t fix my problem, and I tore out that page, more than a little unhappy about the results
