I use this box for storage. There are 18 compartments so plenty of room for different types and sizes. I put a green label on the serger needles so they aren't accidentally mixed in with other machines. Each section can hold 8 packs of needles.

I use the same size box for storing machine feet. Each machine has a separate box that is labeled for the machine.
