Teammates have just three seconds to throw the ball and must pass it three times before attempting to score by knocking over the BakiPin. When a ball goes out of bounds, another is immediately thrown in so the action and exercise never stop! Soft neoprene cover on the BakiBalls takes the fear out of being hit and adds safety. Features rubber bladder and bright colors for easy tracking. BakiBoards are constructed of 5" (13 cm) thick polypropylene, expanded PVC face, and rubber bottom; BakiPins feature foam interior, sandbag bottom, and nylon exterior. Play this non-contact sport indoors or out! Set includes 9 BakiBalls (5" / 13 cm dia); 2 BakiBoards (48"L x 32"W x 32"H / 122 cm x 81 cm x 81 cm); 2 BakiPins (22"H / 56 cm, 6" / 15 cm dia); field layout; and activity instructions.
