Our Story Begins Water Colour Sketchbook A5 200Gsm - 100% Cotton

While the paper quality, binding and cover are just about OK, the paper does not behave like a 100% cotton paper.
If 100% cotton paper is what you are looking for, avoid this product. It is otherwise decent but you can get a equally decent 25% cotton or cellulose sketchbook of the same size and paperweight for a lower price.
