Mini Magnetic Stud Finder with Silicone Strap, Red

A battery-free magnet for finding the screws or nails that hold drywall to its frame, so you know where to drill or hang a shelf. Slide it slowly over the wall: when it passes over a metal fastener it pulls and sticks in place, marking the spot for you. The magnet sits in a red silicone strap with a hanging loop and two holes, as shown. The supplier lists a neodymium magnet with plastic and metal parts. It ships in a package of about 8 x 8 x 3 cm, weighing around 42 g. Contents: one stud finder.
