This is a Louisville Slugger softball catcher's mitt. Although it's a catcher's mitt, it has the same shape as a first baseman's mitt, so it can also be used for baseball first base, etc. It's for softballs. The web has been bent inward using a hot water treatment, so the stiffness when opening and closing the glove is maintained. The core material is also hard, and the leather is taut, so I think it can still be used for a long time. Thank you.
