Great value. Robust. Different colours for different landscapes make them easier to find.
We have been purchasing these fantastic durable balls for well over a decade now. Some balls have lasted 3 generations. The String makes it much easier for some of us to swing/spin & throw the ball further than normal. Plus when your dog comes back (especially as a pup) it’s much easier to retrieve the ball from their mouths via the string, to teach them to release/drop. We only buy more because special Doggy friends met on holidays or walks love them too & we let them keep one for themselves.
