A great magnet for shell work. With the brand name of my expectations were naturally high. I was not disappointed! The shell makes a very Impression of quality and adheres well. When screws on my Car I do not want you to miss. They can be used as storage for Hinpappen screws almost any anywhere. But even in the household I have already used, setting it as a shelf to a simple Radiators have set. The magnetic base is rubberized, making it the foundation is not damaged, still slipping. Knotless product!
