A pop-up shop for the Marni x Porter Collaboration Collection will open at the Isetan Haneda Store in Haneda Airport's Terminal 1 from April 15th to May 12th. The collection features lightweight, functional Porter bags embellished with Marni's original prints. The shop will carry all items from the collection, from the first release in December 2013 to the latest model released in January of this year. The first collaboration, "1ST COLLECTION," features a helmet bag from Porter's signature Tanker series, with Marni's Christmas-inspired print. The second collaboration, "BUSINESS COLLECTION," features a wide range of smart items for both business and personal use. Furthermore, the third collaboration, "CASUAL COLLECTION," offers travel-friendly items such as packable bags for compact storage and clothing covers of various sizes. The latest collection, "FOUR COLLECTION," features four types of bags that express a lighter military style, with Marni's signature color blocking expressing the beauty of color combinations.
