GREENVALE — After seeing their children playing the dodge-ball type game "ga-ga" at a camp in the summer of 2011, fathers and entrepreneurs Corey Gluckstal and David Steinberg decided to create gloves designed to protect the players' hands from scrapes. During the game of "ga-ga," which means "touch touch" in Hebrew, players hit the ball with an open or closed hand, which sometimes results in bloody knuckles. The gloves are now being sold in more than a dozen stores in four different states.
