Glimmies are fireflies that glow when it gets dark. Like magic! The darker the darkness, the more they glow. The package contains a lantern (house) and a firefly figure. The lantern can be opened. If you unfold the house, you will find 3 rooms - a living room, a bedroom and a bathroom. If you place a firefly in the lantern, it will start to glow beautifully. The lantern can be hung. The figure is powered by 3 pcs of 1.5V type 384 batteries and they can be replaced.
