It's main function is to hold thread. Or Hotwheel cars. Sort of like this.
Have a desk drawer full of paper clips, rubber bands, push pins, and other little do-dads you are trying to get under control?
My boys used one of these back when their hot wheel colection was managable. It didn't take long, ebtween the 2 of them, for one small little organizer to become pointless.
I nabbed it.
I brought it to work.
I got raised eyebrows.
But it didn't take long before the realization of how useful something so simple was.
OCD? Not always a bad thing!
Might add: with it being two sided, use the bottom for stuff you aren't needing to grab quick, shut it, and fill the top with stuff you need all the time. Keep the lid off for a quick grab, but near by to that flipping it over to get into the bottom isn't too much hassle.
Oh. And the long section? Perfectly long enough to hold a few strips of staples ready to load and go! And yes, it can even hold pens. Staples on the bottom half, pens on top.
