This is a Nike kids' Dri-FIT shirt. I purchased it last year from the official Nike store, and my fourth-grade daughter wore it twice before outgrowing it. She was about 130cm tall at the time, and it fit perfectly. The size is S, and it's labeled as 140cm. These are the approximate measurements, taken with the shirt laid flat: Length: Approximately 47cm Width: Approximately 35cm Sleeve Length (from underarm): Approximately 4cm It will be shipped via Nekopos (a Japanese delivery service).
