Here we go.....if you look, these are the same, balls but claim different companies. One is Zanies and the other is Holysteed. My understanding is that Zanies no longer sells them under their name and have not for many years. They come from China...for some time I bought them on Ali Express. (after Pet Edge stopped selling them as Zanies)
Everyone sells them a different prices. So, just because you pay more does not mean you get better.
I have things to do...but later on I will look at the Zany website to see if they do have them.
