The film is a blue light cut type that is recommended for people who care about their eyes, such as eye strain and dry eyes.

Since it is a dedicated size for electronic dictionaries, you can use it without cutting it. The genuine Casio film size (4.5 x 2.5 inches (115 x 64 mm) is a little smaller, so it is a size larger by 0.04 inches (115 x 64 mm). (In addition, the larger 0.5 mm at 0.2 inch (116 x 65 mm) will make it perfect for LCD screens, but since the probability of mistaking when applied, the Casio electronic dictionary will have a slight gap between the LCD screen and the frame surrounding the screen. Therefore, if you put the film on either side or side, it will cause the film to be tucked into the gap and the other side will be shortened. When applying, it is recommended that the film is evenly distributed on the LCD screen.
