Great for playing fetch.
The hol-ee balls come in different sizes. I have an assortment. I love to stuff them with treats for my pet and watch him try to get them out. The holes make it easier for my dog to pick up the ball when we play fetch. I match the treat size with the hole size of each ball size. These are sturdy toys and can stand up to rough play.

Great turtle toy
Perfect toy! My pet turtle loves it. He likes dragging things around his tank and pushing them around. I got him this because his old toy was a pvc pipe connector (which he loved to death), but it broke his beak. So I got him this so he could chew it and drag it around. Great and safe alternative

Favorite ball!
My dog absolutely loves this ball. I have a 11 pound mini golden doodle for reference. It is super durable and easy to clean. It is easy for her to get her teeth around and is one thing she has not chewed up.

Sturdy and long lasting.
These balls are a favorite of my Sheltie! She loves to chase after them and catch them in the air. My dog is not a chewer so I can't say how they hold up under aggressive circumstances! They do last a long time .
