Ping-Pong Set of 12 乒乓球 12個套裝

因為小球時代球速越來越快，旋轉越來越強。使得回合減少;而直徑大的球，速度慢，旋轉弱，力量也減弱;而且搽網、擦邊的幾率增加，能增加比賽的觀賞性。

Because in the small ball era, the ball speed is getting faster and faster, and the spin is getting stronger and stronger. This reduces the number of rounds; a ball with a large diameter is slow, has weak rotation, and has weakened power; and the probability of scratching the net and wiping the edge increases, which can increase the enjoyment of the game.
