Nearly silent operation and adjustable alarm Thanks to the sophisticated internal mechanism, the timer runs with almost no ticking sound, helping you focus on work without distraction. The alarm can be activated or deactivated, and the ring duration can be set to 3 seconds or 60 seconds. Visual countdown for all ages The elapsed time is displayed in a sand-timer style visual, making it easy to understand at a glance. Unlike a digital timer, you do not need to read numbers to know how much time remains. Extremely easy to use Set the time by turning the knob. Turn clockwise to extend the time and counterclockwise to shorten it. If you want to turn off the alarm, rotate the knob slightly clockwise and then return it to zero. Interesting rainbow pattern design The timer features a rainbow pattern that is visually appealing in classrooms or as a kitchen timer. The colorful design engages children and supports task completion. Typical uses - Classroom activities, timed transitions, and classroom games - Kitchen timing for cooking, boiling eggs, or baking - Study sessions, homework breaks, and short chores at home or in the office
