I am in the middle of my first build and my case came with these little rings that seem to be made of some type of paper/cardboard material. I assume these are supposed to go on top of the motherboard, and underneath the screws that screw into the standoffs on the motherboard - basically a washer to go with the screws that are used to screw the motherboard to the standoffs.
What is the actual purpose of these things? Do I really need them?
Here's a pic, with a screw and brass standoff included for reference:
