High quality paper, and a very sturdy design make this sketch book well worth the money. It's a little harder to open totally flat unless you're towards the middle, but that's workable.
My only thing was the last page was already splitting, and the pocket in the back was folded funny, but that's just one page and a cosmetic defect that won't effect your overall art. Sad for a $20 sketchbook in a nice box over the shrinkwrap, but it's not a big sad point. I'd still recommend this product regardless.
