The watercolor paper isn't the best in the world, and this sketchbook is more expensive than others. So why the popularity? Well the size is just perfect, it fits well on hand and in a bag, and is not cumbersome. The book is made is with great quality, the pages are not loose, the cover does not feel cheap and holds together very well. I guess for the money it is worth your drawings staying together for ages. The actual paper however, could be better.. it buckles with even a light wash. But still, there is a band to keep the book together. A great product for a student.
