◇ Night Ball J (Same size as soft baseball J ball) ・ 2 dozen (24 balls) ・ "Can't see the ball when it gets dark" "Want to practice even at night" ・ A fluorescent-colored ball that solves these problems has appeared. Its name is Night Ball. ・ Because it has the same specifications as the J ball, you can practice with the same feel as always. ・ Since the rubber itself is mixed with a yellow paint close to fluorescent color, there is no worry of color fading. ・ Let's get into the habit of practicing on weekdays with the limited light of night grounds, home parking lots, parks, etc. ・ Size: J ball size (approx. 69mm in diameter) ・ Material: Natural rubber ・ Weight: approx. 129g ・ Country of origin: China ◆ Cannot be used with electric pitching machines ◆ Please do not use it in places other than designated areas such as the ground.
