Canon 35mm Cassettes
These cassettes fit the bottom-loading Canon rangefinder bodies (and some Barnack Leicas, I'm told).
They have a distinct advantage over the felt-lipped reloads because the film touches absolutely nothing as it passes through open slot of the cassette.
Hence, no scratched negs.
Two for sale @ $25 each, plus $5 shipping.
Buy both and they will ship for free.
I've tested both of these cassettes and both passed.
No scratches, no light leaks.
Smooth transport because nothing touches the film when it's advanced or rewound.
