This is a rotating, colorful duty roster (4-section). It is made with a diameter of 21cm. It has a split pin in the center, allowing it to spin around. How about using it for duty activities or group activities at kindergartens or daycare centers? The mechanism is easy to understand at a glance and is clear even for children. Children can also move it easily. It is also used by adults for work task assignments. We can also accommodate changes in color and size, so please let us know in the comment section before purchasing.
