I read many reviews before deciding which reusable water balls to purchase. I bought these for my six year old grandson and he loves them. They are made of a rubber, maybe silicone, material that hasstood up for a week of playing now on grass and a cement patio. You just fill up a bucket of water, open the ball, it will fall to the bottom of the bucket. You give it a tap and it closes and will be all full of water. It has tiny magnets around the two halves of the ball which hold it closed until you use it. So, my grandson will fill all eight up and then use them one at at time. My grandson figured this out immediately. Of course he likes to have water ball fights with his Dad and friends, but also just enjoys throwing them at targets, trees, the ground, in the air or anywhere around. I bought the eight pack and am going to buy more for my daughter to take on her vacation with a bunch of friends...adults and kids. I would definitely recommend them as we have had hours of fun so far and none have broken at all.

Kids were shocked at what they were and when they figured they were refillable they were having a blast with it and didnt want to stop playing.

These reusable water balloons are so fun. Even little kids (2-4yrs) were easily able to use them. I just wish there were more in the package. They are a bit pricey for just a few.

My niece brought these to a family vacation and the kids loved them. I immediately bought some for my own pool.

Our kids love these. Easy to fill and work great. So much fun

Good quality and very nice replacement for original one

My kids love these! We have had them over a year and still going strong!

I bought this set for my brother-in-law, who has two kids. He LOVED them and couldn't wait to try them with his kids.I also have a set, and love how easy they are to use. The magnets are strong enough to hold them until they need to release.

My toddler loves these! He wants to play every day in the bath.

Toddler grandson enjoyed squeezing balloons and watching them burst.
