These magnetic pockets are so versatile and strong that it's almost impossible to name all the ways they can be used. Each pocket measures 9-1/2" wide and 11-3/4" high and features a powerful magnetic surface throughout the entire back of the pocket. The magnetic backing will hold securely onto any metal surface. The pockets also feature a large clear pocket in the front which can hold up to 2 lbs worth of material. The front pocket also has an insert strip to label contents.
