A stamping machine, heated to an average temperature of 180 degrees, stamps the type of glove onto the pinky. The gold bar pictured pressing into the leather piece is the stamp itself. Each glove must be stamped and embroidered before full assembly and typically receives several stamps, including the Mizuno product quality guarantee. Most of the gloves used by major league baseball players have their own individual embroidery and thus go through a separate line of assembly.
