Works great with Fuji FP100c!

As you probably know, the rollers were of particular importance and emphasis at Polaroid and all but the very cheapest cameras used very well-machined and precise stainless steel rollers, same as found in a 405 or other later film back. When used with the three Fuji packfilms, even the simpler old Polaroid folders produce sharper images than ever - especially when used with FP-100c. As I recall, Polaroid Pro Vivid was nearly the same.
