This colored sand glass looks delicate and lovely, the size is suitable and light, very easy to move and carry. And the cute look of this hourglass sand timer is sure to win the hearts of children. This hour glass can be used as a time-keeping gadget to help children reduce the use of mobile phones and settle down to study in the new semester. This is a very good point. The sand watch clock also makes an ideal toy. You can put it on your desk in the study or in the classroom. It's very relaxing and pleasant to watch the sand flow slowly. I hope that with the company of the sand clock timer, the children will learn more and more easily.
