【High Resilience, Hard to Break】 Made with highly resilient EVA material, these balls are lightweight, durable, and hard to break. These practice balls can be used anywhere and are available in sets of 30 to 100. 【Safe-to-Use Balls for Indoor Practice】 EVA material is characterized by its lightness and softness. Because they are light, they don't fly far, and the holes increase air resistance, reducing their momentum and making them less likely to cause injury. You can use them safely anywhere. 【Size】Diameter 72mm 【Weight】Approx. 20g 【Color】Fluorescent Green 【Material/Composition】EVA 【Quantity/Price】 20 balls...¥1,980 (¥99 per ball) 30 balls...¥2,680 (¥90 per ball) 60 balls...¥5,000 (¥84 per ball) 90 balls...¥7,290 (¥81 per ball) 120 balls...¥9,480 (¥79 per ball) Shipping Method: Shipping is planned via Sagawa Express.
