Thank you. Thank you. This is a popular set item recently. It is purchased by people who have children who have just started playing baseball. Since it is a set purchase, shipping costs are reduced. ◆ 30 used soft baseball balls from batting centers (M-ball size equivalent) ◆ 15 used hard tennis balls (I don't know the manufacturer, etc.) A recent buyer said they wanted to practice fly balls with their child using a knock. It seems that improving defensive skills is essential for children to become regulars. However, the father has no baseball experience and his knocking accuracy is poor, so he thought that practicing with tennis balls and a racket would improve the efficiency of the practice by hitting relatively stable fly balls. (It's a touching story) In addition, tennis balls are used for defensive practice and free batting in narrow spaces. How about adding them to your self-training menu? ※For reference [Hard Tennis Ball Standards - From Wikipedia] Diameter (mm) 65.4～68.6 Weight (g) 56.0～59.4 [Schoolchild J Ball Standards - From Zennanren HP] Diameter (mm) 68.5～69.5 Weight (g) 127.2～130.8 The packaging materials are basically recycled for the sake of the environment. A plastic bag is set inside the cardboard box. First, the soft baseball balls are put in, and then the hard tennis balls are put on top. Please refrain from purchasing if you are concerned about details. Please enlarge the photos, etc., and purchase if you understand. #baseball #softball #softbaseball #practice #used #selftraining #Mball #mball #softball #softbaseballball #softball #youthbaseball
