Pressurized tennis balls are often sold in plastic tubes or aluminum cans. Typically a tube will hold three or four balls. The balls in these tubes are usually pressurized to a pressure of two atmospheres. As soon as the tube is opened, the balls start to lose pressure. For this reason, most recreational players have stopped buying pressurized balls in tubes and choose instead to buy pressureless balls in bags.
