The Hedstrom Playball features fun, colorful graphics of kid’s favorite characters from movies and television. The party pack includes 8 bouncy balls of the same size that are perfect to use as party favors, giveaways, prizes, camp games, neighborhood parties or anytime you need to entertain kids. Ideal for toddlers, older kids, teens and adults. Dogs love to chase and play with them too. Buy a combination of different size balls to create a fun, dynamic experience for games and parties. Party packs ship deflated but easily inflate with any needle-nose hand-held pump (not included). For best inflation results: inflate balls and allow to sit for 24 hours to allow material to loosen and expand. After initial inflation continue to inflate to full size. The amount of time to reach full size will depend on the ambient temperature and humidity. For best practice, wash with mild soap and water before use.
