My "new" needle stash is in a plastic box similar to what
RhondaK has shown.
Plastic "spools" for embroidery floss, are labelled as to type of needle, and size,
with the corresponding needle packages (original) behind. Like a little filing cabinet!
Used needles are kept separate from this box in a piece of quilted fabric,
labelled with a Sharpie as to what they are.
Garbage needles ... go into an old piggy bank, along with old rotary blades and pins.
It'll be a long time til I have to figure out how to truly dispose of them,
but it's a handy and safe storage system for now!
