Why it is on this shelf
Twenty-four inches, the children's size, in red, with a second pack option on the listing.
Twenty-four inches is where the shelf starts. A child of roughly seven to eleven stands inside with the opening at chest height, and the whole thing weighs little enough that they can pick it up themselves after a fall, which is most of what makes a toy get used twice. We like this pair for birthday parties where the lawn is small and the guests are many: two balls, short rounds, a queue that moves. Inflation with an electric pump takes a couple of minutes per shell.
