This  illuminating base is the perfect size for the giant martini glasses that we offer.  This illuminating base will light any transparent or transparent design that is placed on top of it.  It includes a charging adapter.  When you plug in the adapter to charge the base, the red light means that the unit is charging and the green light means it is fully charged.  It requires approximately 6 hours to re-charge.  The base will illuminate for at least 10 hours per charge.
