Is this actual mont blanc legend night cologne or an imitiation of the real thing?

I do not know what you call "Real Thing", but it's definitely an authentic product. Here is an explanation of the meaning of each expression related to the fragrances we regularly use. - Eau Fraiche - It is the most diluted version of fragrance, usually with 1% to 3% perfume oil in alcohol and water. Usually lasts less than an hour. - Eau de Cologne (Cologne) - It is the oldest term for perfume. Light, fresh and fruity, usually composed of 2% to 4% perfume oils in alcohol and water. It tends to be used in fragrances aimed at younger people. Usually lasts for about 2 hours. - Eau de Toilette (Bath water) - Spray with composition of 5% to 15% pure essence of perfume dissolved in alcohol. Usually, it lasts for about 3 hours. - Eau de Parfum (Perfume) - Historically unisex, this term is used to describe fragrances that contain 15% to 20% pure perfume essence and lasts for about 5 to 8 hours. - Perfume - A corruption of the Latin expression "per fumum" (through smoke). It is the most concentrated and expensive of all the fragrance options. Slightly more oily, it is composed of 20% to 30% pure perfume essence. A single application can last up to 24 hours. I hope I have helped you.
