Thank you for viewing. I used this clock by adding numbers to it for children who have trouble reading clocks. This is a handmade item by an amateur. How about it for children who are about to start studying? It's too thick to fit in a mailbox, so it will be shipped on days the post office window is open. - Color: White - Shape: Square - Dial Design: Arabic numerals - Movement: Quartz - Features: Red second hand Arithmetic Grade 1 Grade 2 Grade 3
