Mizuno Field Grister Series Model Number: Y-12500 This is an authentic first baseman's mitt. The hand in the photo belongs to me, who is 168cm tall. The softballs in the photo are J-league balls. Softballs are size 2. *For reference... It's a size that can be used without any problems by children up to about 155cm tall. It's a bit small, so I think it's okay for elementary school students in the lower grades. It's a good-shaped, authentic first baseman's mitt. It shows signs of use, but because of that, it's a glove that can be used right away. There are no tears in the leather or broken strings, so you can use it from the day it arrives. Although it's for softballs, I think it can also be used as a catcher's mitt. First baseman's mitts and catcher's mitts are gloves that are limited to specific positions, and they are expensive, so this glove, of course, is a used item, but I think it's in good enough condition. For children who have the opportunity to play first base but only have regular gloves, how about a first base-specific glove? Not only the quality of play, but also the sense of security and motivation that comes from playing with a first baseman's mitt will lead to good plays. For those who are wondering about buying a new one... This mitt is highly recommended. Also, recently, I have transactions with people who purchase catcher's mitts and first baseman's mitts for their teams. Thank you for your consideration. It will be shipped after being polished with Mizuno's Strong Oil. If you have any questions or would like to see additional photos, please feel free to comment.
