Have a few questions about the 20 x 24 Polaroid.

1) How much per shot was the film or / is the cost of the film if it is still available? (I did a quick search and could not find any film.)

2) Does the film for the 20 x 24 come in packs like the small Polaroid film did? Or is it single sheets that must be loaded in film holders?

3) How exactly is it pulled or rolled out to pocess?

Thanks
