This auction is for a lighted magnifier for the original gameboy.  I am not sure what brand this item is.  It has not been tested.  One of the bulbs is missing, but the remaining one likely will need to be replaced, as this item is several decades old.  The cover for the battery compartment is still intact.  There appears to be 2 batteries still inside the device that I do not know how to remove, so they are still inside.  A piece of the battery holder has broken off, but can most likely be repaired with super glue.
