This Coaster is meant for illuminating your glas at any party or event. The light is automatically switched on/off depending if a glas is placed on top of the coaster or not. The light will only be on, if a glas is on the coaster. Power comes from a commonly used 2032 button cell battery, with a runtime of at least 7-8 hours.
