Perfect for young players moving up in the game, the Diadem Stage 1 Green Balls are 25% slower than standard tennis balls—giving kids aged 9–10 the control they need to develop solid technique and confidence. Designed for use on full-size courts, these ITF-approved balls have a lower bounce and softer feel, making rallies more enjoyable and less frustrating during practice and match play.
