This is a BLUE CROSS brand black jacket from Narumiya International, size M for children. It was an expensive piece of children's clothing, so the fabric is sturdy. It's black denim. The lighting in the photos made it difficult to capture the color accurately, but it's a calm, subdued black. The brand's character is featured on the button decorations and charms, and there's also a single stone on the back. It is a used item and has been stored for a long time, so please refrain from purchasing if you are sensitive to such things. I bought it but hardly used it, and it has been stored in the closet, so I think it's a beautiful, good-quality item. The size is children's size M.
