Premium Material: This kids clock is made of premium materials, including an ABS backplate, plastic frame, and high-definition glass. The smooth contours are free of burrs and seams, minimizing scratches. The high-definition glass prevents dust from entering the clock's interior. [Silent Design] This wall clock features a brass movement that runs silently, ensuring it won't disturb a child's rest; it uses an AA carbon-zinc battery (not included); do not remove the battery if not in use for extended periods. Educational and Fun: This silent kids wall clock is easy to read and features vibrant colors, making it an educational gift for children. Easy to Read: The 12-hour and 24-hour numbers on this kids wall clock are clearly visible, and the inner ring changes color every five minutes. The 10-inch diameter and enlarged colored numbers help children quickly find the correct time, reducing reading difficulties. The mirrored design prevents the colored numbers from fading, maintaining clear readability for a long time. Versatile Use: This kids room clock is suitable not only for preschools, schools, classrooms, and elementary schools, but also for children's bedrooms, teen rooms, living rooms, and nurseries. Whether it's a birthday or Children's Day, it's an ideal gift for boys and girls.
