If the majestic owl symbolizes wisdom, what better way to display that than a glowing beacon of light coming from the bearer of wisdom itself? After all, enlightenment can come just from a simple spark of light. This light up Owl Necklace uses a 3/4 diameter LED light that fades on and off in a bright shade of red. It is powered by 2 CR1220 lithium cell batteries which are included and replaceable. The LED light in the Glowing light up Necklace is surrounded by a gorgeous silver filigree owl shaped wish box. The light up Necklace hangs from a 18″ silver chain. Also included is a replacement set of batteries.
