Traditional 110 films were pre-exposed between frames, a feature intended to make it easier and more efficient for photofinishers to print:
Whether new 110 films such as the Lomography or Fukkatsu releases have similar pre-exposures I have no idea. Kinda doubt it.
I like getting those extra couple of mm's in my Pentax auto 110 using non-perf 16mm film slit from 35mm.
