They're still available, here is an auction for a lot of 18, ending tonight. An alternative for storage (and not nostalgia) are short wide screw-top cans, widely available online.I always thought the metal ones were pretty neat, I never liked the plastic ones. If I had thought about it at the time I would have saved myself a batch of the metal ones.
When I was doing photography back then I was buying 35mm film in 100' rolls and loading my own so I wasn't buying small rolls of film very often.
