Each ball is in the original ZIPPO case. The balls are unused. One of # 3 ball is likely a bit yellowish compared to the others (I think).
There are some age deterioration on the ZIPPO cases but not much.
The plain/unprinted cardboard outer box is clean and in good shape except tear surface (pointed by the red arrow in a photo).
Please zoom all photos carefully to see the vintage condition. Just add to your collection.
The color may vary due to the devices/monitors and reflections.
Please ask if your have questions, doubts and/or concerns since I may have a mistake by accident. I ship the item in a recycle/used unprinted or printed advertised box, sorry but not a new one. Thank you for watching.
