|One of my hardware boxes|
For the jewelry box I've added some hinges and a clasp at the front then finished it off with metal corners on the lid which give it a more solid look. Not that it isn't solid enough but I think it complements the cutouts.
One of the things to remember when using the hardware is that you need at least 2, 3mm pieces of cardboard to screw them into. If you want to put something on and you've only used one 3mm piece of cardboard then you'll need to add a small piece of cardboard to the inside so the screw don't come through.
Some of my clasps are for boxes and some are for small cabinets.
