Where to get empty film rolls?

[twotwo]

I'm looking for empty film rolls for a school project. Where can I find them? Thanks!

you're talking about empty film containers, film canisters, or film strips? because they all come in rolls haha.

i've got quite a few of each (except film strips), but the film canisters are rather flat (see here) after i've been done with them. on the other hand, you can try to ask the photo printing shops where they get their film developed and go to the source to see if they could spare you some of these.
