Made of waxed paper this is an above average sized sickbag, and will hold a fair content. There are no instructions what to do with it though, either before or after being sick. 1994 - Thanks Lads (Right)

This one doubles as an envelope which, if unused, can be sent away with photographic films for processing. They haven't wasted an inch of space in this marketing ploy.

Update 2001 - Qantas are on a winning formula with this idea. Again they have produced a sickbag which doubles as a photo development envelope. They still havent missed an inch of space, even using the sides*! And the best thing? After all these years its still only $5.95 to have a film developed. 2001 - Thanks Ben & Steph (Below)
