Guerlain Cologne Du 68 100ml 80% Full Batch 9S01 Vintage.  Pre-Owned, approx 80% Full.  No Box.  Discontinued.  I am saying 80% full--might be slightly more, but I don't like overstating perfume fullness.  Anyway the level is shown in photos.   

I also have a tester about 90%+ full with no cap, not listed yet, let me know if you'd rather have that one.
