If you use a cutter to open the box, do it carefully so as not to cut the product. Carefully cut the label on the back and then open the lid.
Inside the box you will find the sticker rolled like a tube, so as not to have edges that spoil its appearance when it is mounted.
Along with the sticker you will also find the set-up instructions to help you with the process. If something is unclear, please watch the installation video where each step is carefully described.
