I´ve seen the Partagas sallies in a plain dressed box once. It was in Barcelona and I had the good luck of visiting a very nice Club Epicur member - he had the most impressive collection I´ve ever seen (and I only saw half of it). He gifted me one Siglo VI, 2 months before anyone I knew got any and it was one of the best cigars I ever smoked. He had everything in his collection, tons of custom Diademas and Salomones, Partagas 155 humi, cigars from 1940 (Hoyo in glas tubes) etc etc. He also had a box of Partags Salomones, the cigars inside was wonderful, dark and oily - I got a lump in mu throat when looking at them (true). I also have had contact with another collector who says he got a box. With all this said I can´t say for sure they where real, but I´m pretty sure the Club Epicure member wouldn´t buy any falsarios (he had been in Havanna many times and is a veteran smoker and collector).
Edited: Sorry, the ones I saw in the dressed box was with regular bands.
