The level of a ping pong ball indicates the quality, durability and suitability of the ball for different levels of play. This parameter is most often expressed using the star system, which is widely used and recognised by the ITTF. 1-star balls are intended for recreational play, less demanding training or children's play. 2-star balls have a higher bounce uniformity and better sphericity, so they are used for more demanding training purposes. The 3-star balls represent the highest quality - they are officially approved for competitive and tournament play, and are distinguished by maximum manufacturing precision, balance and durability.
