Pitch
We attach a pitch to grasp the ball well.When we play in the gym,we attach a duct tape of both sides on  taping finger because a pitch dirties the gym.We tend not to attach a pitch when we play handball in PE lesson. A pitch hardly come off clothes.A pitch can come off hand by the pitch cleaner.
