"Just by Coloring, Your Brain and Mind Will Be Revitalized! More Mandala Coloring: Irritation, Stress, and Depression Disappear" Hideki Wada / Keita Sagaki Price: ¥926 After purchase, I colored a little (see photo 7). I didn't have time and stored it on the bookshelf. I won't have time to color it in the future, so it's partially colored, but if anyone would like to use it, please do. Please refrain from purchasing if you are nervous or seek perfection, as it has been stored at home for many years."
