Too small
Much smaller than it appeared to me in the picture. I did not read the length as I should. I would not have bought it if I saw it before purchasing. My 18 month old grandson now has a new toy.

The tennis balls are very well made.
Color: Yellow, Size: 20 PACK
Bought this bag of tennis balls for my son’s dog. He has a tennis ball launcher that he shoots and she runs to get the ball and bring it back.
Perfect training toy!

Great value.
Color: Yellow, Size: 20 PACK
They bounce and they float. Color is bright. Great for my dogs. I let my dogs use these instead of the ChuckIt brand when unsupervised because they tend to get punctured.

Great color but destroy easily
Color: Orange, Size: 20 PACK
These balls are easily visible and excellent in situations where green balls may be difficult to find.
I only take these balls out to play fetch. The balls only last a couple of fetch sessions before being destroyed.
