Recently, I ordered a remote for my Nikon DSLR from Amazon and it arrived in a very peculiar box. It just happened to be a perfect box to use to create this DIY.
Cardboard Box with a removable insert.
Using your craft knife, cut the cover off the box, and cut slits into the cardboard as shown.
The amount of slits you cut depends on the size of your box and the size of your rings. My box was pretty small, and I have a few statement rings so I needed more room.
Add your rings!
