old or new sweet or biscuit tins (Alcester Lanes End B14)

I make crunchy popcorn for gifts and send them to friends and relatives in the post. Have had some smashed glass jar incidents recently and thinking about using tins instead, all shapes and sizes welcome. I need ones that haven't had the lids bashed about too much (as air tight as poss) and not heavily rusted (a bit of spotting is okay).

Prefer to collect a few tins in one go rather than lone tins as I cycle. If you live local and are eager to get rid, feel free to drop off at B146bd at your convenience.

Thanks Freeglers!
