100 Rounds Refill Balls Ammo Compatible with Nerf Rival Gun, TiopLior Foam Bullet Ball Replacement Refill Pack Fit for Rival(HIR, High-Impact Rounds)

They work great and are cheap.

Purchased these to use with a homemade slingshot my 10 year old made and they are really great.

One of my cats loves to play fetch. I'm pretty sure she is actually better at it than most dogs, lol. We started with a soft cat toy ball, and figured out that she prefers nerf balls by accident. They are easier to throw, and bounce in different directions. They are also small and soft enough for her to carry in her mouth.I would definitely recommend to anyone who has a beautiful ball fetching cat!

I love seeing good deals from 3rd-party companies of the foam rounds that I need for events.

As said nice balls they're firm and fun to play with, shoots good bounces alot, hurts a bit if shot point blank but overall some nice balls.

I love these nerf ball so much because I can throw them around my apartment and my one very active cat who is a orange tabby likes to go and chase them around and sometimes he'll pick them up and bring them to me just so I could throw them again they're not harmful for my pet and he gets exercise from them it's a great product and I really like it.

My dog's love playing with them but they are so soft the dogs end up chewing them into lots of pieces and then I have a mess to clean up so they only get 1 at time and not every day. They will last forever

These perform exactly like Nerf rivals. They're a tiny bit softer, but the same size and shoot 90% as reliably. And most importantly, there are a fraction of the price. This huge bucket has lasted us many months!
