The Fuji FP-100B is a peel-apart-type instant black and white film with an ISO speed rating of 100, for use with Fuji's PA-45 film holder, Polaroid's discontinued 550 film holder, or Fuji's identification cameras. Each package of FP-100B 4x5 produces ten 108 x 85mm prints with a 95 x 73mm image area.
This black and white ISO 100 film can be used in virtually any light with similar results to be expected, as opposed to Fuji's FP-100C film which prefers daylight (or heavily-corrected artificial light).
Even in the digital age, there's something special about observing a fine example of one of these little prints. Beyond its professional applications, it is a unique offering in today's world for the hobbyist seeking something special.
