Mizuno Select 9 Series Model Number: Y-17600 This is a full-fledged first baseman's mitt. The hand in the photo is me, I am 168cm tall. The soft baseball in the photo is a J-ball. The softball is a size 2 ball. *For reference... It's a size that can be used without any problems by children up to about 155cm tall. It's small, so I think it's okay for elementary school students in the lower grades. It's a good-shaped, full-fledged first baseman's mitt. There is almost no feeling of use, so the pocket is still shallow and the glove is still a little stiff. There are no tears in the leather or broken strings, so you can use it from the day it arrives. Although it is for soft baseball, I think it can also be used as a softball catcher's mitt. First baseman's mitts and catcher's mitts are gloves that are limited to a specific position, and they are expensive, so this glove, of course, is a used item, but I think it is in good 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 the play, but also the sense of security and motivation that comes with 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 add photos, please feel free to comment.
