NITTAKU 3 stars Premium 40+ Table Tennis Ball (Pack of 6)

Perfectly round - these balls are characterized by excellent roundness and consistency. Made in Japan from special poly material that is produced exclusively for Nittaku. Very durable - these balls are safer and much more durable than their predecessors. A new generation of table tennis balls that replace celluloid balls. Hard as Celluloid - The biggest complaint about poly/plastic balls is that they are not as hard or stiff as celluloid balls. Nittaku Premium 40+ matches the hardness of good old celluloid balls and although it is a bit slower, it still delivers performance that is closest to celluloid balls. ITTF approved - this means that these balls can be used in all ITTF tournaments and are of the highest quality. This is also the official ball of the Liebherr 2017 World Table Tennis Championship Professional Choice - Popular with many professional table tennis players over other poly/plastic balls and unofficially considered the flagship in its class."
