Manufactured in Italy and supplied to school gyms, day care centers and camps, this mega ball encourages hours of interactive group play. Made of heavy-gauge vinyl with a non-slip ribbed surface, the 4-foot and 2 1/2-foot diameter ball invites activities such as climbing and balancing on top as well as rolling, kicking and bouncing. Capable of sustaining weights up to 300 pounds, the balls are made using a unique roto-molded process that totally eliminates the seam splitting common with other balls. Ball inflates quickly with the air pump (sold separately). Ages 8 years and up with adult supervision.
