metal tins

Hello:
I am looking for small metal tins. Sixe can be between 1" to 3". The bottom and the top both need to be metal. I can find "Bindi" boxes in aluminum, but they have plastic tops.

I want to drill small holes in the tops, put dessicant granules in the tins, and put them in my closed storage containers to keep my stock of silver jewelry, silver raw materials, etc., from tarnishing. I read on another forum that dessicant will do this. The dessicant has to be dried out in the oven periodically, and all-metal tins will make it easy to do that (I have a LOT of storage containers, and will need to make up many tins of dessicant.)

Has anyone seen these?
