Follow the instructions
The mailbox lettering came in about 7 days.  It was exactly what we wanted. I read the instructions and watched the video several times to be absolutely sure things went well. I applied the lettering on the mailbox before installing it outside.  I did use masking tape to make a hinge as one video suggested, that made it easier to keep straight. Just follow the instructions and you should be satisfied with the product.
