The product under consideration is described as impact protection foam buffers. They are safety padding made from cushioning plastic foam. The buffer will come in two color varieties, a yellow body with black striping, and a white body with red striping. The three-dimensional shapes come with self-adhesive backing to allow them to be affixed to a clean surface for impact protection, though some may be non-adhesive and will either be pressed into place or secured with glue. Per your submission, they will come in three lengths: one meter (straight length), five meters (rolled into a coil), and 50 meters (rolled into a coil). These buffers are intended to protect walls and corners from damage caused by heavy impact and to prevent injury to individuals by cushioning obstacles, such as low-hanging pipes.
