I have a glass jar on my desk. It was at one point a jelly jar, but now it holds an assortment of fasteners, screws, nails, and washers. If I open it up and take a whiff, you can still smell some strawberry, almost like the instruments are scented.
All the pieces come from old furniture, electronics, or picture frames that are no longer used or are broken, or else they were extras (IKEA likes to do that).
The lid is that picnic blanket gingham pattern, red and white, and can be clicked if you press down on it.
While I do on occasion use the nails and screws that the jar holds, those moments probably only come up once or twice a year, but the jar is still allowed the valuable real-estate of my desk.
I like to look at it, and if I ever do need them, they’re close at hand.
