The Chartreuse glass has a little of the edge of the base shaved off like someone did a repair for a fleabite perhaps- no one will notice. The darker green glass has a tiny area on the outside of the rim that may have been also smoothed to repair a tiny nip- won't cause issues. The other 2 have no flaws that I can find. All 4 are good to use to drink from or display, but.
This is for 2 reasons- We sell antiques / vintage goods, therefore they are used, I provide photos of the exact items and not stock pictures so you can always see the exact item you will get.
