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!
