We are offering 4 Inch Mirror Ball Reolite. Fill up an entire room or vehicle compartment (or plane or boat cabin for that matter) with sparkling light. When the sun, a spotlight, a flashlight, or laser, is directed at one of these, hundreds of moving spots of reflected light are created everywhere, just like in a ballroom or party setting. Four inches in diameter, with attachment cord for hanging. There are at least a hundred highly refective glass squares covering a hard inner core. A less expensive version I almost got talked into buying several years ago used plastic squares, but in the real world nothing reflects intense light as well as glass (If plastic tiles become scratched, or modified by intense sun, forget it). Very popular with car & trucklovers (even light airplanessport them), hanging from arear-view mirror. Also look stunning in a sunlitkitchen or bathroom window or for use as a christmas tree decoration; really, anywhere you have good sun exposure (backyards, patios, pool areas, gardens, or even hanging from trees). Some people use them as an out-of-reach hanging item in ababys room as a visual toy, and to brighten the general area (understand, though, not for the little character to actually play with.this is glass!!) And last, but hardly least, they can be useful as a party decoration.
