This sketchbook far exceeded my expectations for quality. The paper is thick and smooth and the marker colors just pop on it. The plastic insert sheet they include gives peace of mind for preventing any bleed through. I love the ability to tear out pages and the spiral binding seems very secure. Very happy with it.
Also, the Ohuhu Customer Service has been excellent. My initial sketchbook arrived damaged and they sent out a replacement right away. As a first time customer I am very impressed with their sketchbooks, markers, and service.
