My other order from http://www.specialtybottle.com/index.asp arrived, too, yesterday. I found a place where I can order tins! The large ones don't have a solid cover (clear plastic), but I don't mix paint in the covers anyways. I laid some large pans inside to show how you could easily get 12 pans with room for travel brushes.
The smaller ones are the exact same size as an Altoids tin! And I think the larger ones are the size of those large Altoids tin that cost like $7.99 during the Holiday season in the winter--if you can find them (we looked last Christmas--no luck). Shipping is high--but they package really well--box inside of a box with peanuts and everything wrapped (I also got a couple of glass things). Even tho the shipping was high (11.64)--the tins and jars were so low that it made it worth it, for sure! The large tins were 80 cents! And the smaller ones were 64 cents. No minimum order. I am one happy camper!
