A great little gadget designed to make a table centerpiece from a simple wine glass. The little floating light simply sits inside a wine glass, you then add a paper shade, there's one included but you can easily make your own in whatever colour paper you wish, & because the light is warm white LED it's very safe; no fire risks! It comes with a micro USB (Universal Serial Bus) charger that simply plugs into the light & will fully charge it in about an hour, & give 3 hours of light. Because the light 'floats' around it makes lovely moving projections making it look like a flickering flame.
