Sorry if this has been covered before. I searched vaguely but didnt find any topic covering it.
I would like ideas on good smallish containers for holding various spices, sugar, tea, coffee, etc.
Would like plastic i guess so they dont clank about on the little shelf in the camper
Thank you
How small are you looking for? I typically carry larger containers for the frequently used seasonings like salt and pepper, but smaller containers for things like oregano, thyme, nutmeg, etc. For the small containers, pill organizers can work great depending on how long you travel for. Specifically, look at things like this and this.

EDIT: Ah, just saw you're in a camper, so probably looking at something a little bigger. :)
spice containers

I bought these from IKEA. They are stainless, clear insert in the lid and have a magnetic back. They hold just under 6 ounces.

I use these little plastic ones. They fit upright in the drawer of my camp kitchen, they're humidity proof (I don't know if they can be submerged though), and they're small so I can refill them between trips and not worry as much about the spices getting old or stale.
Simple, easy, cheap.
