This is really great. I was sort of getting tired of the really meticulous adult coloring books so this book having like open pictures to color was a nice change. The story line are pretty funny as well. I love coloring in these while i'm bored at work to pass time (im just a receptionist, I don't do much) or I color in them while watching netflix I loveeeee coloring while watching netflix. It's just a nice calming, mindless activity that allows you to still focus on what your watching as well and keeping your hands busy. The pages are thinner than other books I've had, but I have not noticed an issue with bleeding through when using markers. Which brings me to my next point, one thing I do recommend with this book is using colored pencils. Maybe that is normal for some of you colorers but in previous books using markers never resulted in an issue because the coloring spaces were so small that the marker lines didn't show. When I first used this book I went in with marker not thinking of it and didn't like that I could see the marker streaks. and if the markers streaks overlapped it would get darker. So I'm sure that colored pencils will fix that issue. It's not at fault of the coloring book, just an observation I found. Overall, I would highly recommend this coloring book.
