I love, love, love these watercolor journals. The paper is great, while not super-thick, they absorb a ton of liquid and take quite a beating (they do buckle a little, but not enough to distort the image or prevent the book from shutting) but the paints are SUPER VIVID when dry. The size is perfect- big enough to do something detailed, but not so big you can't throw the book into your bag or painting kit and be on your way.
