WAIWAI X01 / Crook-Crook

Decrease the time children spend on playing games, and thus, pay more attention to learning. Moreover, it reminds
children the proper time for rest when they are learning. This is the design purpose of WAIWAI—offering children a
reasonable and appropriate way of growth.
Suppose you sit on the stool, you can set the sitting time by pressing the ring which is on the leg of the stool. When
the ring return to the original position, one leg, which the ring attached to, starts to shrink, and in this way, it
announces the time for you to rest.
