SIMPLE AND 3D DESIGN: High-quality ABS back, classic black metal frame and unique 3D digital design make up this alarm clock. Special three-dimensional figures are large and clear. The time can be easily checked from any corner of the room. Wide range of uses: With a diameter of 10.8 cm, the dial is a practical and modern addition to headboards, desks and bedroom shelves. An excellent birthday or Christmas gift designed for children, boys, girls, teenagers and the elderly.
