Fujifilm Instax square film is perfect for those people wanting a bit more than a credit card sized pic, but not wanting to go all out and buy an Instax wide. The sheets are the most authentic in comparison to traditional Polaroid pictures. I love the black border because its not your average run of the mill white border ones. AND HONESTLY they have many styles and designs in the instax mini, and a decent selection for the wide, but not the square. I think i have seen 4 different kinds of Square film you can buy, this being one of them(so far) But Fujifilm is always coming out with new stuff so im sure there will be more very soon. The black frames also are a bit nicer if you wanted them to stand out more wherever you are placing them. For instance if you just had one taped to your wall, it would have a more official, framed appearance.
