I purchased these ping-pong balls thinking these where at least 1 star balls. I would rate these balls at -1000 and that's being kind. If I were to look up cheap in the dictionary I would expect to find a picture of these balls in it. I have made many purchases on Amazon and I never have been displeased until now. My recommendation is not to purchase this item. You could not sustain a game of ping-pong with these balls due to the lack of bounce I highly suspect if you could play beer pong for the same reason.
