They are perfect for helping my brain relax!!! and reduce the stress! (meditation)

You must be kidding! they are absolutely nothing to us!!! they are for baby not adult!!!!

I am professional artist and I use it for practice and fun..!! XD

they are not really my "thing" or even consider to be called art.... I rather creating my own line art and coloring it!

why they called this "adult coloring book" since it doesn't have any adult content????

This make me feel like I am happy child again!

These are very good for anyone who are practice coloring and shading art!

uh... i never heard of them... can you explained? (comment below)

other opinion? (comment)
