The design inspiration of this pencil case obviously comes from the blue toy bus model shown in the picture. It cleverly combines fun and practicality, adding a unique charm to stationery storage. The appearance of the pencil case adopts a blue tone similar to the toy bus. The main color is calm and lively, which is suitable for students and can show the personality and taste of the user. The size of the pencil case is designed just right. It can accommodate enough stationery supplies such as pencils, erasers, rulers, pens, etc., but it will not appear too bulky, which is convenient for students to carry to school or home. The lid may use a magnetic or snap design to ensure the safe storage of stationery and facilitate quick opening and closing. The top or side of the pencil case may also be equipped with a police helmet-shaped decoration as a finishing touch, further strengthening its police theme. Such a design not only makes the pencil case look more vivid and interesting, but also inspires children's respect and yearning for the police profession.
