Thank you for viewing. This is a game-used spike from Miyazaki, a key player for the Yokohama DeNA BayStars, who won the Japan Series last year. As you can see from the photos, it has Miyazaki's original mark, making it very cool. I believe professional players' spikes are rarely available on the market, so this is a valuable item. Regarding the size, it is a custom-made item for a professional player, so the size is not indicated on the spike. I have listed an approximate size. Please understand. I have not used it since I obtained it. I have stored it in a dedicated case. *There is red clay on it, so I believe it was obtained as is after a game. Thank you. #YokohamaDeNABayStars #GameUsed #Autograph #ProfessionalBaseball
