This is a hardball hand guard. It's the same model that Shohei Ohtani wore during his time with the Hokkaido Nippon-Ham Fighters. When I purchased it, it was described as being for both right- and left-handed batters. I haven't used it in games or practice; I bought it as part of a collection, but I'm selling it to organize my belongings. Thank you. - Brand: asics - Color (outside): Red - Color (inside): Blue
