Not for a strong destroyer
Golden retriever destroyed this quickly but I’m starting to think he can destroy all things.

Quite small.
These were way smaller than I imagined based on the photos. Those were obviously ai generated photos that don’t even look like the product at times. They are pretty flimsy and I wouldn’t buy again. My dog will tear this apart in 2 min. But it’s a good size to throw around I guess or maybe for a much smaller dog that doesn’t also want to chew.
3 stars because we will get some play out of them and there’s 2. Just know what you are getting
