A size-free notebook-shaped smartphone case designed with the theme of "colorful pop". It goes well with almost any smartphone. (Can be used with smartphones within 150mm in height and 74mm in width) When you open it, it becomes a single picture, and you can see colorful patterns from any angle, which is eye-catching. It has a design that you have never seen anywhere else and is especially popular with women. Cards can also be stored, so it is convenient to put frequently used cards such as regular subscriptions and electronic money here. It comes with an even more nice mirror. The back is made of a sliding type, so you can easily take pictures by raising it up when taking photos. (Attached with a special suction pad) Note: Some smartphones may not fit the size. Please check carefully when purchasing. * Smartphones with a height of 151mm and a width of 76mm or larger cannot be used because they will protrude. * Models with the camera lens in the center cannot be used. * Even if the lens is in the upper left corner, models with too long lenses at the bottom cannot be used. * From iPhone 13 onwards, the lens part will hit when sliding, so please purchase a hard case separately and wear it before attaching this smartphone case.
