As of my last knowledge update in January 2023, I don't have specific information about Viktor & Rolf Flowerbomb In The Sky in a 50ml size. Flowerbomb In The Sky is a variation or limited edition of the iconic Flowerbomb fragrance by Viktor & Rolf.For the most accurate and up-to-date information, I recommend checking the official Viktor & Rolf website or contacting authorized fragrance retailers that carry Viktor & Rolf products. They can provide details on the latest releases, including Flowerbomb In The Sky and its available sizes. Limited editions may have specific release periods, so it's advisable to check with official sources for the most current information.
