The working principle of the product is that the two moving elements are wound around one another in a linear manner by moving the moving part at the top. The thin strips on the tape and the thin long bars inside the main body facilitate the winding process. The movable part on the top is connected to the system by means of a thin long rod through the system. The region similar to the letter E on the left side of the Main body allows us to adjust the size of the material to be wrapped, has the ability to create 3 dimensions (thick-medium-thin).
