It can holds a lot of balls and it is made out of a high enough quality of material to stand up to vigorous play for multiple children. Your children will love playing with the balls in the pit. Its flexible enough not to be a hazard to younger children. The coloring is attractive and appealing to the eye. Even slightly older children can get in it without it tearing up easily. It is truly a portable playpen. But it is not the type of play pen for kids to sleep in, it is a play pen to PLAY in. This product is made of waterproof polyester (not plastic). Air can still get through this material as it is a fabric. Please remember that the balls are sold separately. You are buying the playpen only. I believe your little ones will love this.
