What you need:
A foam box (I got mine on clearance at Hobby Lobby for a dollar)
X-acto knife
Tape measure
Rings!
-----
This is NOT recommended for little kids. Using an x-acto knife can be dangerous and result in injury.
First you get the box and all of the tools you need together. The box I got was 4x4" so there is room inside for whatever you need it for! I'm going to use mine for bobbypins and hair clips. :)
And then measure the width of the ring and cut at least a 1/2 cm bigger than the ring in the spaces that you want your rings to fit in. I recommend marking it with a pencil so they are even before cutting into the foam. The cuts don't have to be perfect aligned with each other due to the height and width of some rings (plus it makes it look cooler)
My cuts are a little sloppy because I didn't mark them with a pencil to make sure they were even (which is why I recommended it in the before step)
But in the end it looked fabulous! And it's functional so that's even better.
