This is a racing silk worn by Naoya Hashimoto, a former jockey at Urawa Racecourse. It is unopened, but appears to have been used. It's difficult to see, but it looks like there's a signature on it. As a bonus, a Urawa Cherry Blossom Sho towel is also included. #UrawaRacecourse #SouthernKantoRacing #JockeySilk #RacingSilk
