The box measures almost 4 by 3 inches. About a half inch tall. Age is indefinite but is considered vintage. The quality of the kit for modern use is
unknown. Interesting old item. Photos are of the actual item.
The last two photos I had held it up to a light for 30 seconds and then snapped a photo in the dark. Also the product shines all alone in the dark with just being exposed to natural daylight.
