I don't even know why I have these... These are cartridge type film where 16 sheets come in a cartridge. You pull the tabs and next exposure is ready for shooting. On its back, it says "For all film pack adapters and cameras using 523 film packs". This film is slightly expired.... Sept 1979. ...and it has STRONG smell of cigarets! (ew) I remember it came to me this way. You get two packs. One factory sealed and everything intact. Another in a light proof bag and I took it apart. I think it's missing a few exposures. I got this from someone in APUG. I have no idea how it was stored or if it will even work. I'm pretty sure you can't get these developed at Walmart. Absolutely no guarantees except to say you get one sealed pack and one I took it part. $10 SHIPPED, please. PM me if interested.
