I Don`t Know What I`m Coloring Book: 25 Mystery Puzzle Drawings Revealing Themselves, Lines And Spirals, Don`t Peek - Just Color Inside The Line, ... And Adults, Unique Gift For Overthinkers

These are fun for just mindless coloring. Keep in mind though the lines are fine and some are very close together but not touching. You will need a sharp pencil or fine liner pen and a steady hand. Also good lighting. I tried this at my dining room table and had to get an extra light on it.

A great unique coloring book style. I love not knowing what the end product will look like and even if I figure it out it's still enjoyable. I love drawing with pens and this is relaxing and mindless. Would definitely recommend!

I LOVE this coloring book! It is a bit intensive, but super fun. I plan on framing the images and making a collage for my wall! I bought a pack of nice black sharpie pens to use. If your eyes get strained easily and/or you have unsteady hands, this probably wouldn’t be the best for you.

This is perfect for people who love to doodle and color but don’t want to think about what their doodling.

I was hoping this would be a great brainless option for getting into flow and being rewarded with a reveal at the end, but honestly it's just incredibly slow and it makes my eyes hurt. The lines are so small that it takes a lot of concentration to ensure you stay within the line and the nature of the hidden design means accuracy matters. It's tough on the eyes to make sense of which line you're coloring along.Maybe it'll work for others, but I didn't find it enjoyable.

Yea, I don’t get it. Color inside the lines but where does the line stop and then start again? The concept is great and the pictures are cool but it’s a little confusing for me. Glad it wasn’t expensive!

The book COVER advertises 25 mystery spirals. There are only 8. The rest are squared pictures, not spirals. I was not aware that type of blatant false advertising even allowed.

This keeps my interest and is incredibly satisfying!

I love it. It's fun an easy.
