A set from Dollish, the adult coloring series by Nelco neco Chika Akasu. It is a set of loose coloring sheets, not a book. The pictures show doll-like girls in girly fashion and outfits.
The set has 5 sheets of A4 line art, each with a different design. They are printed on paper made for coloring, so the lines do not bleed with colored pencils, watercolor or alcohol markers. Alcohol markers show through to the back of the sheet, and the paper may warp if you use a lot of water with watercolor.
