Hello IFee, The privacy filters have been developed so that you don't have to cut anything to size. In fact, you shouldn't cut the privacy filters to size. Our privacy filters are designed according to inch size. All you have to do is pay attention to the correct inch size and select the right size and then the privacy filter will fit perfectly on the MacBook screen and hold perfectly thanks to the magnets. Where does it not fit if you want to cut the film to size?
I hope this has helped you. PLEASE DO NOT CUT TO SIZE!!!
