This is an acrylic stand case with clear pockets. The size when closed is approximately 17cm x 13cm. You can store acrylic stands, keychains,缶バッジ, bromides, etc. that are about 13cm tall. There are three clear pockets, so you can store a lot of items. How about using it as a carrying pouch for your "oshi-katsu" (supporting your favorite idol/character)? It has a quilted core inside, providing cushioning. The inside is white satin (the fabric appears wavy in the photo due to the lighting, but it is actually plain white satin). Please understand that this is a handmade item.
