The hourglass set made of sturdy beech wood is a great helper for kindergarten, elementary, and preschool children to visualize time. By watching the flow of sand, children effortlessly train their sense of time. It's ideal for brushing teeth, doing homework, cooking, or keeping track of time while reading or playing. At 14 cm, it's perfectly sized for little hands. The hourglass set, featuring time intervals of 1, 3, 10, and 30 minutes, is designed to enhance understanding of time and duration, and it also impresses visually with its high proportion of natural wood combined with modern colors, making it a standout piece in the classroom or children's room. It offers a particularly pleasant tactile experience thanks to its rounded shape.
