The extra large numbers on this attractive bedside alarm clock make it easy to read during the daytime. But wait, there’s more to this clever clock than meets the eye… it absorbs natural daylight and uses it to glow at night. Visible even across a dark room, you’ll never need to get out of bed to tell the time again! Made of plastic. Uses 1 x AA battery (not included). 13 cm L x 7.5 cm H x 3 cm W.
