teavana used to have good tins, but last time (1yr ago) the rubber lip thing was not as rubbery anymore, more rigid. they did not leak anything into the air (i have a strong earl grey that is a test to any container
i got some cheap containers similar to ones from imperial court, the rubber/plastic ring was rigid=wont make a good seal, and not well glued, came off!
nowadays i just get airtight containers from target (usually sterilite) they dont leak anything, dont smell like plastic, only thing is theyre transparent (i keep in a closet, but even so not enough)
only advice is to keep the herbals (chamomile) in their own, because the damn aromatics/smells are really really tough to remove even from the metal tins (i am now at a 3rd wash with overnight soaking, 1 still smells...)
french jars (the ones with a rubber O ring on the lid and clamp to close) look good but you have to check that it is a rubbery one, and the rubber is well squished all around (some are made bad).
