SKY BOUNCE Yellow Handball Set Of 12 (1 Dozen)

I bought these for my dog, Bub. Sadly, these are not as durable as some brand name racquetballs, which I use with my heavy duty chewing dog. He was only given one of these and he decimated it within an hour. I'd guess they're okay for the actual sports for which they're designed, but I was hopeful they'd survive Bub. Alas, it was not to be.
