Time Management for all ages! This unique timer gives a visual picture of elapsing time. As time elapses, the red disk gradually disappears in a clockwise direction. When the disk is gone and time is up, an optional audible alert is available on the back using the volume control dial. This timer is ideal for anyone who struggles with time. Requires one AA battery (not included). Size: 7.75" x 1.75" x 7.75".
