Especially in current times, hygiene is extremely important. Proper handwashing is a skill that needs to be learned to effectively remove all bacteria, viruses, and germs. Keep hands under water, lather all areas for 20 seconds, rinse off the soap, and dry your hands. This timer not only helps children adhere to the recommended time to ensure their hands are thoroughly clean but is also easy to use. Simply activate the timer with the large button, and the countdown starts while the large LED light shines red. Once the recommended time of 20 seconds has elapsed, the light turns green. The timer can also be used for brushing teeth, with a set brushing time of 2 minutes. After 60 seconds, the red light blinks three times to indicate that half of the time has passed. A wall mount is included for easy installation with adhesive tape (included). Ideal for nurseries, kindergartens, after-school care, daycare centers, elementary schools, medical practices, and families with young children. Battery 3 x 1.5 V AAA not included.
