I received a well-sealed white poly mailer at my house, and inside there was a small box with thorough instructions for application, as well as a small cloth to clean the camera

They came with a little cleaning cloth.

and there's no mechanical interlocking feature to keep the assembly low-profile, it can be dislodged by a sharp impact, vigorous wiping with a cleaning cloth or nearby magnets, so keep an eye out for that

Love the little cleaning cloth they came with; all packaged nicely

Nicer than the cheap-o plastic covers I had previously purchased.

n’t be difficult.
