This is a t-shirt from Seiko Matsuda's 2023 concert tour. The size is M. Please refrain from purchasing if you are looking for a perfect item, as it has been stored at home. To fit the package within the size that can be delivered by post, it may be folded in half while still in the bag for shipping. Please be aware of this before considering a purchase. I have many other Seiko Matsuda goods for sale, so please feel free to comment if you would like to combine items.
