There are holders with which you can put the Fuji 8.5 x 10.8cm Instant Peel-Apart Pack Films (which are still in production and hopefully will be for a long time!) to a 4x5 graflock back:
There are also similar ones from Polaroid which you can find used sometimes.
I recently bought one of these as I read that the 4x5 Fuji Instant films go out of production, even if I have some of them still in my refrigerator (not freezer).
For checking purposes the smaller image size (that is not centered in the 4x5 image frame, at least for the Polaroid holder) might be useful.
Best regards, Heinz
