This reel has a powerful magnet at its end, and is therefore great for making any small item that can be attracted by magnets disappear. The reel does not have a “stop” and has a metallic clip on it so it can be attached to your belt or to a pocket. It is made in plastic and has a diameter of about cm 3,2 (1,37”). The thread is made of nylon and is about cm 61 (24”) long.
