Poly-PG Ball duplicates the feel, texture, and weight of a rubber PG ball, while eliminating the inherent PG ball issues with shape distortion and air leakage. Elastic-shape memory helps avoid blow-outs if ball is moderately overflated; seam-free design gets rid of awkward misshaping or potential for punctures. Durable ball is constructed from roto-molding, which converts liquid vinyl into a seamless inflatable ball that is bouncy and highly elastic. Ball measures 7 inches in diameter. Sold individually. Color is randomized (sorry, no choice of color). Please note that ball comes shipped and delivered deflated; inflates easily with use of air pump or inflation needles (sold separately; see Item # 087922).
