The Edu-Play hourglasses are super! The set consists of 5 hourglasses that are smaller than the Edu-Play hourglasses of individual sizes. 16 cm - which is about a hand span high - instead of 30 cm at full size. Nevertheless, hourglasses are really great! The colorful, colorful filling appeals to children. They are made of durable material. And thus the inner Sanduhrkörper can not break (children are often not very delicately), they are covered with an additional clear plastic tube. We use it for a variety of activities: homework, flute playing, quietly sitting etc ... the children they accept gladly timekeepers. And love it by the way, to turn themselves and watch the sand during trickling. Really good!
