TIMER / toothbrush

TIMER

This is a design that can prompt children to master the time for teeth clean by the change of color. Most of them don't have enough patience to grasp the correct time for brushing. The pattern portion of the TIMER toothbrush handle is made of temperature-sensitive material, the longer the child hold the toothbrush handle, the higher the surface temperature will be, thus causing a color change of the pattern which belong to the temperature sensitive material portion. When the color changes from original light pattern to red, the brushing time meets the basic length of time which is about 3 minutes.
