This Sketchbook is surprisingly amazing. Our 13 year old is using it in conjunction with the new 120 count Ohuhu Alcohol Brush Markers, and so far it's doing exactly what you would expect it to do, it's far exceeding my expectations. The paper is very thick, thicker than any sketchbook we've purchased her prior to this, and much better than any mixed media. No bleed through to the following pages. It's a very sturdy sketchbook also. Especially like the tear lines so she can remove any art/mistakes without tearing the pages completely. The cover is holding up well for being dragged around a lot up to school letting out. The quality of this and Ohuhu Markers is definitely helping our daughter have a great outlet for her creativity. Images include a 'possibly' finished drawing of her own creation (had to sneak it out of her room to take a picture), also the backside of that along side the following page, to show the lack of bleed through.
