There is this little sticker plastic thing that is located at the bottom. We are going to now use our pocket knife, the back part of it because we do not want to cut or rip that plastic section.

The tip of the knife should be used to help peel it and then the back of it should help lift it up.

It's okay, this is super sticky, so it will re-stick when you put it back together. Once done, go ahead and tuck it up (see last photo in this step) and move on to the next step.
