These double-sided papers have a solid-color on both sides. Packages contain either an assortment of color combinations in each package, or a single color combination. Double-sided papers are essential for some types of models where you don’t want just the typical white reverse side to be visible. Maybe it’s an origami box where the inside and outside of the model are different colors, or a robot body folded from a single sheet of double-sided paper where the contrasting colors specify different parts of the armor. Whichever the case, double-sided solid paper enhances your piece and makes people notice!
