4x5 instant film-pack holder - Polaroid
This is the 4x5 version, not the one that takes FB100C Fuji. I've had it for awhile and I don't think I'll be using it. As far as I know, Fuji has stopped making the 4x5 packs (just so you know), but if you have some, or some older Polaroid 4x5, this is what you need to shoot it in a standard 4x5 camera with a modern back.
Perfect shape, used about 8 months ago. No problems known, but money back if you find any. Photos possible if you need them, but it's a pretty standard item.
