Size is perfect for tossing
Color: Multicolour
Great to toss for dogs. But if dog chews it much, they don't last long.

Durable and great color
Color: Orange, Color: Orange
I’m so happy with these orange tennis balls! They’re the perfect size for Roxy’s ball launcher, and the bright orange color makes them super easy to find—no more losing them in the grass! Roxy goes wild for them, and they’re holding up really well even with all her chomping and fetching. If you’re looking for fun, durable balls that stand out, these are a winner!

Cheap but good for what we do!
Color: Dark Blue
I wouldn't play tennis with them -- not that quality. However, we use a chuck-it thrower for our pooch and it's the perfect ball. When she's rips them open it's no big loss. Chinese.
