I have an old instax print, taken in 1998 or so and it is an integral film. The frame of the print is textured paper and the back is paper with the (now empty) chemistry pods. Never done instant photography, but have some prints (polaroids, instax and kodak instant).
Unless it has changed, instax should be an integral type instant film. So far, Fuji and TIP are the remaining players of the integral instant film?
...SHould get myself into instant photography someday, it's attractive (except for the wallet) and magic.
I stand corrected then...
