Now you can get the giant ball experience at a fraction of the price. Sportogo has taken the sturdy PVC-style bladder that is used with our other balls and have imprinted a baseball pattern directly onto the bladder itself, eliminating the need for a covering. Please note that we cannot silk screen this style ball. Each ball has a maximum size of 30 inches but will get tight at a smaller size (roughly 24 inches) allowing you to adapt it for use with smaller children. And at a weight of only a little over three pounds this light weight ball will allow for hours of fun no matter what your age. Each unit comes with one ball, plug, plug remover, hand or foot pump adaptor, set of instructions, and a 90-day manufacturer's warranty. To inflate the 30 Inch PVC Baseball Sportogo recommends that you use one of our double action handpumps that can be found in the REPLACEMENT PARTS section of our website. For proper inflation instructions please see the FAQ section of our website.
