Any way of using Fiji Instax film in original Polaroids?

Does Instax use a fundamentally different method of development, or is it a size issue?

Yes, it does employ another photochemical process and a different layer setup. It cannot be used for principle reasons in any Polaroid camera that uses integral film. (That is one-piece film.)

For technical reasons it cannot be used in any other Polaroid camera.

Hi
I am not sure if u wonder where to buy film for the original Polaroids, but if so, check out this store. Thats one of my favourites to buy for analogue-camera n stuff.

(I am sorry if my english isn't the best. I am new to this forum and I have a few problems in understanding the technical terms in english. But i promise to do my very best )
