The table tennis balls that you see in the store are 38mm. They are hard to find in table tennis stores because they are not used in tournaments. The ITTF which is the overseeing organization of table tennis has changed the rule in 2000 to use the balls of size 40mm. This new rule has disappointed many players. I have seen serious players buying 38mm to relive the glory they had before the rule change.
I don’t know the quality of this Big City ping pong ball. They are cheaper. You may have to pick the right ones out of the 144 to play. The second hand quality ping pong balls don’t offer good bounce. Sometime this has to do with the table also.
