Crayola Optical Illusions Coloring Book, 40 Coloring Pages, Gift

Great book, thick paper, bold lines

This book is really great. The pages are thick (my 6-yr-old colored hard with marker, then held up the back of the page to me and said "Look, it doesn't show through!") and good quality. The pictures are legitimately cool - the black-and-white shading is such that no matter how you color it, it's going to turn out looking awesome (easy win for young kids!). The only downside for me is that about half the pictures are geometric patterns (cool), and about half the pictures are kinda weird, overly grotesque creatures that I don't care for. I'm not sure why some of the creepy monster ones are intermingled; I'd rather just have the geometric ones. It's an odd mix.

Fun to color

I will enjoy colouring these pages I am anxious to start colouring. Great service. Thanks

This was a unique coloring book with some great designs of optical illusions. There were a variety of types of optical illusions, some more complex than others. I had a relaxing time choosing the colors for each design. The paper was thick enough so my marker pens didn't bleed through too much. The black lines designating boundaries were thick enough so I didn't have to worry about accidentally coloring outside the lines. I got many hours of enjoyment from this coloring book.
