You can buy a 2-pack of Polaroid 600 film on Amazon
As far as I know, Amazon is the only place you can buy Polaroid 600 film in a bundled 2-pack.
Fujifilm teases new square-format Instax film
Umm, so this is the best news so far from Photokina 2016. Funny that analog film like this can still make such a big splash among the numerous digital advances being heralded around Photokina. Anyway, it looks like Fujifilm is going to release a square-format Instax film. Obviously this will go head to head with The Impossible Project's revitalization of Polaroid's square format instant film. Hopefully, Fujifilm prices their instant film competitively.
