First of all they come with the pump and the extensions that go on the pump to blow up the mini basketballs. It Is a hand pump, but hey it's a mini basketball it's not that much effort. They blow up quickly and stay blown up thru alot. I had 4 toddlers playing with these for hrs. Then the teens came in and was playing ruff like usual and these really held up they lost a little air not very noticable but all I had to do was pump it back up takes a few seconds. Now the colors are great so brite and they have the basketball patterns on them. No choke hazards on the balls themselves. I am purchasing more there the size they say they do come in different sizes and all the sizes are the same great balls. Two thumbs up!!
