This unique origami paper is a treat for the eyes. Its opalescent properties combine with the paper s surface, color and iridescent light to give a vivid rainbow-like effect to the viewer. Each pack contains blue, green, orange and pink sheets that are constructed in smooth or crinkled finishes. The sheets are 4-1/2" or 5-7/8" squares. The small 4-1/2" packs contain sixteen sheets with four of each color, and the large 5-7/8" packs have eight sheets with two of each color.
