Hearth & Hand Catchall Trays, set of two, $12.99
Like the name suggests, catch-all trays can be used to hold just about anything. I have one for jewelry on my nightstand, one for paper clips and push pins on my desk, and one right next to the door for keys — along with a lot of other ones scattered throughout my space. They're super practical for keeping your knick-knacks somewhat organized, and they serve as nice decorative pieces, too.
