The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Surprisingly sturdy at 3¢ each, better than expected for a large 1,000-count bulk spoon box 🥄📦
📝 Summary For about 3 cents per spoon, I expected these to be extremely flimsy. They are still disposable plastic spoons, but they are stronger than I expected and a very solid value for a 1,000-count box. ✅ Pros    • Very low cost per spoon.    • Stiffer than many bargain disposable spoons.    • Reinforced shape helps the handle resist bending.    • Useful for parties, lunches, quick meals, and everyday convenience.    • Serious value for the money if you use disposable utensils often. ⚠️ Cons    • Not as sturdy as metal utensils or thick premium plastic spoons.    • Still disposable, so the waste tradeoff is worth thinking about.    • Hard frozen foods may still need a little care. 🥄 Review At this price per spoon, I expected these to feel like the cheapest, flimsiest spoons possible. They actually surprised me. The design helps a lot. The handle has a shaped, reinforced feel, and the spoon does not bend as easily as many low-cost disposable spoons I have used. It is not metal-spoon sturdy, and it is not the same as a thick premium plastic spoon, but it is definitely better than I expected for the price. For normal meals, snacks, lunches, parties, and quick cleanups, these are completely practical. They could even handle softer ice cream with a little effort, which is more than I can say for some thin disposable spoons that fold almost immediately. The main selling point is the value. A 1,000-count box at this price makes sense if you want disposable spoons around the house or for gatherings. There is still the environmental side to consider, but from a convenience and cost standpoint, these are a strong buy. 💡 Quick tips    • Good for parties, lunch bags, office kitchens, crafts, and pet-food scooping.    • Keep some in a car, picnic bin, pantry, or emergency kit.    • For hard ice cream, let it soften slightly first. 🧑‍🍳 My take I bought these expecting very basic spoons, but they are better than that. They are not fancy, but they are sturdy enough, useful, and priced very well for how many you get. I would buy them again.
