Unsure if the lights have ever been used (the way the cord is folded it is possible the lights are unused). However the box is severely damaged and stained, The styrofoam tray is stayed and damaged.
Please refer all the pictures as they are a part of description.
There is only 1 replacement bulb. Writing on the box. Cord is discolored (pinkish). 2 bases at top row are different from the rest of the bases on a wire (the tray slots are bigger as well, thinking they were made this way?) The green on those light bulbs is peeling as shown and not as bright as the rest when lit.
See pictures and feel free to contact if any questions before buying.
