I will ignore comments asking for a price reduction as this is the best price. Standard table tennis balls are 40mm. There are also 44mm balls designed for seniors, but in reality, even though they are for seniors, the speed doesn't change much, and they are still small for those who are truly new to table tennis. For those people, we have these: 55mm Jumbo Balls These are sold in a set of 12 balls. These will reduce the number of missed swings when playing with children. Limited stock remaining, so order soon! Shipped via regular mail. Search Keywords: Table Tennis, Ping Pong, Beginner, Ball, Table Tennis Ball Butterfly, Nittaku, Victas, TSP, Yasaka Showa, Mr. Argus
