Double-sided printing on thin paper. If you color a design, the one on the other side of the page gets ruined. However, that won't be too disappointing because it most likely looks pretty much like the one you just colored. You see, there are only 3 distinct patterns in this book that get repeated constantly, just varying in size. Unlike the review before mine, I have only colored ONE page and haven't touched the book again in months. Most disappointing coloring book purchase yet.
