Approximately 1 year and 3 months ago, I ordered and purchased this through a limited production run on the Yokohama DeNA BayStars official website. It's made of the same material and design as the helmets actually worn by player Toshiro Miyazaki in games. This is the home game specification. Size is L. I usually wear an authentic cap size 59cm or 7 3/8 with a bit of room, but this L size fits perfectly. It's for a right-handed batter, so the ear flap guard is on the left. The helmet storage bag with the sticker of Toshiro Miyazaki's name is also included, of course. Please check the images. It's the same helmet as the one worn by player Toshiro Miyazaki in games, only the size is different. You can't buy this anymore, so it's extremely valuable and rare. Especially for those who are particular about authenticity, this is a rare find, so it's first come, first served! I've only tried it on a few times indoors, so it's almost new. I've kept it stored in a cool, dark place for almost the entire time. However, since it's been a little over a year since the purchase and it has been handled by someone, I think the condition is very good, but please understand that it's not brand new. I've included images of the official data from when it was sold, so please check them. Regarding the away game specification, there was a minor change last year where the star mark changed from yellow to white, but I haven't heard of any changes to the home game specification, so I believe the design remains the same for this model. However, I can't say for sure, so if you are concerned about the details, please research thoroughly before purchasing. Thank you.
