Troubleshooting all the bad reviews: User Error!It is two sheets. Remove glass, peel apart top mat and bottom. Remove yellow wax paper and stick that sucker on after you figure out the direction the magnets are printed.Magnetic sheets are printed in horizontal lines. If it doesn't stick, turn it 90 degrees and try again. It bonds solid!Printing on glass was hit and miss for me. PLA sticks to it as if they are made for each other. Remove the top mat, flex and enjoy the crackle of your print coming off the surface.A must have along with your glass for other mediums.
