Thank you. This is a set of popular soft baseballs and hard tennis balls. Shipping costs are lower than buying them separately, saving you about 800 yen. Customers include those with children who have just started playing baseball. To deliver clean balls, all the soft baseballs have been washed. ◆ 40 used soft baseballs from a batting center (M-ball size equivalent - the balls in photos 3, 4, and 5 are the items for sale) ◆ 15 used hard tennis balls (I don't know the manufacturer, etc. There is some fine dust and dirt attached.) A recent buyer wanted to practice fly balls with their child using a knock. It seems that improving fielding skills is essential for the child to become a regular player. 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. (A touching story) Others use tennis balls for fielding practice and free batting in a small space. How about adding them to your self-training menu? ※For reference [Hard Tennis Ball Specifications - From Wikipedia] Diameter (mm) 65.4～68.6 Weight (g) 56.0～59.4 [Junior J Ball Specifications - From the All Japan Soft Baseball Federation HP] Diameter (mm) 68.5～69.5 Weight (g) 127.2～130.8 We basically use recycled materials for packaging for the sake of the environment. A plastic bag will be set inside the cardboard box. First, the soft baseballs are placed at the bottom, and then the hard tennis balls are placed on top. Please refrain from purchasing if you are overly concerned about the condition.
