Excellent Condition - Tennis balls are basically brand new looking and acting. They bounce great and are very yellow and clean. As close to brand new as possible. Perfect for tennis play. They are what I'd expect to see after maybe 1 time being played. Dog balls are cheaper because they might have a minor flaw but are still new looking.

Dog Tennis Balls- a great ball but has color change. The bounce is still great. My own dog gets these balls.
