"Ball Itself" is a none-axis tape dispenser. With the tension of the elastic material, the tape can roll when put in "Ball Itself." There are bulges on the inside of the valves, which can reduce friction to make the tape rolling smoothly. The tape can be directly tugged into the tape dispenser because "Ball Itself" is flexible.
