I obtained these a few years ago. They are Disney coloring books. Available for individual sale (all prices include shipping). Set of 3: 900 yen (approx. 300 yen per book) Set of 2: 650 yen (approx. 325 yen per book) Single: 400 yen (approx. 400 yen per book) Color pencils are included with the coloring books, making them convenient to use right away (^-^)v Easy and convenient for use while traveling. The coloring books are approximately 14.5 cm tall and 11.5-14.5 cm wide. How about for young children?
