I use recycled clear plastic food containers for hardware. Some from
herb or parmesan cheese containers. These are free, air-tight,
light-weight, unbreakable, wide mouthed, and I can easily see what's
inside. Sometimes the labels are difficult to remove--I soak them
overnight, then clean off any remaining residue with kerosene. So far
I only have a dozen, but the wifey have been saving them for me.
