From the dieline, a design/packaging blog I read regularly.
A student designed a package for ilford 120 rollfilm, that can be folded into a pinhole camera for said film. Supercool, although it wasn’t clear whether this was an actual product or just a design concept. Check the link for more images and info on the project.

It’s too bad that it doesn’t look like you can print the instructions anywhere. It looks like it might have just been a design project. Good find anyways though.
great idea
