Trimmer blade storage:
When I buy trimmer blades, I tend to buy multiple packages when they are on sale for 40-60% off, but storing multiple packages can take up a fair bit of room. Last year I started removing all of them from the packaging and storing them in an extra 4x6 Iris photo case that I had. It's working great so far (and I have somehow managed to not cut myself, lol.)
It sits in my "extras" cabinet with my misc ink cartridges, photo paper and such.
