This pack of Purple 600 Reclaimed Series Instant Film from Polaroid contains eight sheets of film for use with Polaroid 600-series cameras. Featuring an experimental purple chemistry made from reclaimed factory materials, this ISO 640 film offers a dreamlike instant film look with a glossy 3.1 x 3.1" image area and traditional white borders. The emulsion combines Blue 600 chemistry with Acid Red dye for unique, blooming purple shades. Each shot develops in 10-15 minutes after exposure, and the film should be stored in a cool, refrigerated, but not frozen, place before use. It has a built-in battery to power 600-series cameras, but it can also be used with i-Type cameras.
