This Gnome with Lights Lighted Water Lantern decoration is made of plastic and measures 7" L X 3" W X 9" H. It requires 3 AA batteries and has a 6-hour timer that repeats every 18 hours. The swirling glitter is continuous, and it should be gently flipped to keep the glitter from settling too much. The decoration also includes a USB cord, though no adapter is included. The adapter should not exceed 1.5 amps.
