Thank you for viewing. This is a Koki Niwa model uniform worn by the Japanese national team players at the 2017 World Table Tennis Championships. Please note that it does not have the JTTA mark, so those who participate in tournaments, etc., should be aware. I am selling it because I no longer have the opportunity to wear it. It will be a commemorative T-shirt, so it is a rare item. The size is M. It is a design that suits both men and women.
