If you are buying these balls for your dogs, please note - Our used tennis balls are all branded balls from the major manufacturers, so they all have the durable thick rubber cores that are only available if the balls are branded balls from the major manufacturers, so they will not fall apart in no time, like the poor quality unbranded balls that are made with cheap and nasty rubber, typically manufactured in China & Hong Kong.
These companies pay ebay extra listing fees to be placed at the top of the listing searches, which makes it look like they are selling a good product, but they are not !
It is obvious that these balls are cheap and nasty brands / unbranded new balls that are dangerous for dogs, as they are made using cheap and nasty rubber, they split apart, causing dogs to choke !
Plus the knap that they use to cover the balls is also cheap and nasty and so is very abrasive, which causes damage to dogs teeth !
