[For Children's Education] This is an important educational tool for training students in their sense of time. You can use a sand timer to time your child's study time, toothbrushing time, or meal times. Sand timers are easier to understand than clocks and are more helpful in helping children become aware of the passage of time. Plus, compared to a plain clock, children might like a colorful sand timer more. Recommended for parents struggling with their children's fussiness! [Wide Application] Perfect for use as a kitchen timer, classroom timer, or exercise timer (yoga or psychological training). It can also be used as a home office decoration. The colorful hourglass makes a great gift for children or friends who need to manage their time. Furthermore, its exquisite appearance makes it a beautiful addition to any home decor. [High-Quality Materials] Durable PVC, borosilicate glass tube, and sand. Black protective cover, not easy to break. [Counting Time] Each hourglass has a different color representing a different time. There are printed markings on both ends of the hourglass. A deviation of 10% is possible at 1 minute, 3 minutes, 5 minutes, 10 minutes, 15 minutes, and 30 minutes. Please note that there will be time discrepancies and it cannot be used as a precision timing device.
