If you are lucky enough to still have pack film the Rollei 6008 cameras are brilliant with it. Maybe you'd like to try and use this as a base to convert to an Instax back for the Rollei? I've seen it done, but don't know any specifics.
I have several of these available. I'm showing pictures of just one. Some will have a few sheets of film still left in them. Some will be empty. I doubt any of it is still viable, but you never know.
PS. if you really want to shoot with Fuji pack film - I have a secret stash for me personal use. Email me and I maybe willing to sell a few packs - I have the 100c and 3000b but I do know market rates.
