Instructions for using Laptop Skin: (1) Wipe the surface of the laptop from dust or grease. Make sure the area of the laptop you apply the skin to is 100% clean. (2) Cut off excess edges with a sharp Stanley knife or scissors by using the laptop as a guide. To make trimming easier, you can first mark the excess edges with a pencil and a ruler on the backing paper of the skin. (3) Peel off one edge of the backing paper and fold it upwards. Then apply this small peeled side to the edge of the laptop. (4) Take a squeegee, ruler or credit card to smooth the skin forward while peeling off the backing paper at the same time (5) Finally, take a cloth and wipe with light pressure to remove any air bubbles.
