The broom of square tube / 方管型扫把

In daily life, as we can see, the broom wire is designed to be cylindrical shape, and each of them is circular cross-section, which is similar to our overall hair shape. Therefore, the intertwining contact surface is bigger, and it is easier to twine around our hair. The point of design is that the broom wire is changed to square bar shape, and it is quadrilateral cross-section. Besides, the tube wall is four-sided diamond shape, so it will reduce the contact surface and the chance of twining around our hair effectively.
