This is a Christmas concert T-shirt from Seiko Matsuda, 2024. The size is M. It is new and unused, but please refrain from purchasing if you are looking for a perfect item, as it has been stored at home. To fit the package in a size that can be delivered by post, it may be folded in half while still in the bag for shipping. Please consider this before purchasing. I also have many other Seiko Matsuda goods for sale, so please feel free to comment if you would like to combine items.
