A storage case is provided, including two shell bodies correspondingly foldably and unfoldably connected to each other. Each shell body includes a main body and a color ring arranged around a circumferential edge at an end of the main body, and a color of the color ring is different from a color of the main body. When the two shell bodies are correspondingly folded, the two color rings are substantially disposed parallel to each other in intervals and located at opposite end edges remote from each other of the two shell bodies. When the two shell bodies are unfolded and located neighboring to and parallel to each other, the two color rings are disposed, substantially, neighboring to each other on the same level.
