Sharon Rivera 3 The balls are a perfect size for my 2 and 3 year olds and they are very bouncy. They are rubber so easy for them to hold.They came flattened but came with a pump. However the pump Didn’t come with a needle but like an inner tube pump. I wasn’t able to blow them up because the wrong needle was sent. Thankfully I had a lot of pump needles at my house so I was able to use that to blow up my balls but if I didn’t have them then I wouldn’t have been able to blow up the balls. The add even says it comes with a needle but the top was wrong.But other than that the balls are nice!
