Adrian,
Our local Chicago (insert cheezy store name here) dollar stores often
have plastic boxes used for holding other things like mints, sewing
kits, toys, etc. plus, on the metal end 6" dia. "danish" butter cookie
tins that were worth a buck. The cookies were naturally made in China
and even the local squirrels, well known for their love of all things
sweet, would touch 'em. But the tins were nice. You might also check
local military surplus stores for empty decon kits like this:

seen these locally for $1.50 ea.
