Calvin Klein is one of the biggest American designer brands that has been involved in the world of perfume since the 80s, but with the release of CK ONE in 1994, CK really got its own identity. CK ONE focuses on unisex sharing, the perfume bottle is a simple frosted glass bottle, subverting the gorgeous packaging of previous perfumes, showing the American aesthetic to the world, just came out to create a sales record of 58 million US dollars, in Australia 20 years later, CK ONE is still the sales champion of the Australian perfume market. In 1996, CK launched CK BE, which is different from CK ONE, although it is a neutral fragrance, CK BE is more suitable for young men to use, creating a clean and fresh feeling after bathing. CK perfume is not expensive and is a good choice as a beginner perfume.
