This is a set of 4 OSMOSIS items. The size is listed as "one," which is equivalent to a size M. They are new and unworn. I only opened them for the photos. All items still have their price tags. The total price of the items is 34,760 yen. Each item has a unique and attractive design. To keep shipping costs down, I will fold the items compactly for shipping. Also, I have a pet cat at home, so please refrain from purchasing if you are sensitive to this. I love this brand, so I got these items in a lucky bag. They are all great and could be the main item in an outfit, but I'm selling them because they are similar to items I already own.
