Seiya Suzuki, who is having a great season in Major League Baseball, this is a uniform from his #51 era. Worn 2-3 times. Although the size is listed as M, I measured it and it's almost the same size as a current uniform size S (see photo 6). It's very clean with no stains, but the "m" in the front alphabet is chipped about 0.5mm (see photo 5), so please refrain from purchasing if you are concerned about this.
