Volume 11 of Dollish-G, an adult coloring series by Nelco neco. It is a set of loose coloring sheets, not a bound book. The drawings show doll-like girls in girlish fashion and outfits.
The set contains five A4 sheets, each with a different line drawing. They are printed on special coloring paper, and the lines do not smear when you use colored pencils, watercolor paints or alcohol markers.
The set comes with two usage notes: alcohol markers show through to the back of the sheet, and the paper may warp if you use a lot of water with watercolors.
