I'm expecting a bottle of Balenciaga pour Homme in the next week or so. From the research I have done I believe they never reformulated this one but opted to discontinue it instead. Probably accounts for the powerhouse strength which was indicative of that 80's early nineties era.
Also the bottle and box you have is the same as it was back in the nineties and they usually change that with reformulation. Nice pic's by the way.
