Fun Express Rubber Rock Bouncing Balls - (12 Pieces.) Rubber. 1 1/2" (38mm)

Daughter had a rock climbing party and these bouncing balls worked well as part of party favors. Yes, there was an unpleasant scent upon initially opening box but I just left balls out on table to air out and that worked fine. Kids love the way they bounce in irregular directions, makes for lots of fun and laughs

Great way to entertain youth! The shape of these does not let the ball bounce straight so each time it goes a different way. Parents can sit back and laugh at the fun each will have. Very well made and tough material for hours of fun.

Somewhat goofy balls. They are not round but they do bounce and roll though not like a round ball. The older kids love them,Now a caution: These balls are small enough to mostly slip through the toilet paper tube so be sure there are no under 3's around them because they are a choking hazard.Now my concerns:1. They are not well finished -- many of the seams have not been well trimmed and some have not been completely sealed.2. They have an odor that is not pleasant. I hope it disappears with time. So be prepared when you open the box.

I keep buying these things where ever I can find them the cheapest. I first purchased them a few years ago to go in favor bags for a kids birthday party. However, I recently discovered my cat loves, loves, loves these balls and likes to run after them when we throw them. They are large enough so that she can't swallow them. Unfortunately, my dog likes them equally well and started chewing on them, not good. Not a big deal now as we have trained our doggie to not even touch them and keep them out of her reach.

Nice assortment of bouncy balls!I am doing an "Its The Great Pumpkin Charlie Brown" theme for my sons 1st birthday. I think these are perfect for party favors. "I got a rock."They are smooth and pretty. Obviously, bouncing them and catching it is going to be a chore as they are odd shaped. But the kids will love them. I am very happy.

Sturdy, decent size, with an odd shape that gives this balls an unpredictable bounce. Perfect for my ricks and minerals class! Fun for the rockhound in your life!

Great rock climbing party favors. The kids loved how the balls bounced in random directions because of the shape. They are a little small, but perfect for a 5yo birthday.

These were a big hit at our minecraft themed party. Careful around smaller kids though, they can easily fit in a toddler's mouth. They bounce great and look really cool.
