Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
This is an amazingly intricate coloring book with a nice story. I was so surprised when I received it because it is quite thick. I've started coloring, intending to give it to my 7 and 8 year old Grandsons, however it is so thick and detailed that I think they'll be 21 before I finish!
I'm using pencils because markers show through. They do make some indentation through the paper but it does not spoil the page. The paper is of excellent quality.
This book is of excellent value and quality for the price.
