You can have hours of fun with our StikBall with Strike-Zone Target! A little smaller than a baseball, Stikball has a sticky outer surface and a mold-able middle. Rare back and throw it against walls, windows or the included Strike Zone Target and measure your accuracy against other players. When it hits a flat surface, it â€œsplatz!â€ And there is NO RESIDUE when you remove. Includes two Stikballs and strike zone target. Are you in the strike zone?
