I used to see these in those plastic capsule vending machines when I was a kid (in those days, they were two or four quarters, as I recall). Pretty sure those were the bottom end versions of the HIT, and they came with a mailer to send the film for processing (and get a "free" roll back -- this was long before the color labs that did that to lock in customers). My mom would never let me have the quarters to try to get one (they were about one in ten capsules in the machine, and you couldn't see what was sitting on the exit hole).
The film for most of them was 17.5 mm wide with paper backing, with 12 exposures, as I recall. You could cut unperfed 35 mm (or get three strips, each about three reloads long, from 120) and cut strips from 120 backing paper to make up rolls, if you have two spools.
