remove the film underneath and there is adhesive.
stick the plate on and its more solid, as these are modular, the can be taken apart.

you should have asked this in /ohm/ or something.
very silly to make a thread about it.

electrical shielding kinda like a ground plane on pcbs, but it turns all the traces into little capacitors with the plate

Solder a wire to it with a jumper and use it as a ground plane when necessary. It's probably more useful if you're breadboarding audio stuff.
