Are you entrenched in folding that insect model you've always dreamed of, or a similarly complex model which requires a large sheet of origami paper? These 13.8" solid-color packs contain sheets where every sheet is the same color. We have both 100-sheet and 50-sheet packs. All of the origami paper is from Japan and non-toxic (though we wouldn't suggest ingesting it). Ganbare with your creation!
