Not many children will be able to resist this activity! And there is a wonderful “control of error” here—if the flashlight doesn’t light up, something is amiss. Our woodworker has carefully routed individual slots for each piece of the flashlight. The maple tray has rounded corners and tapered ends for easy grasping; 10½" x 4" x 1¼" high. The 6" plastic flashlight is the perfect size for the young child to grasp and unscrew; it is available separately or with the tray. Batteries included. Ages 4 and up.
