Thats a hot lippy!
I have a feeling one of the reasons Fafi had cheap printed plastic packaging on the make-up itself, is because of all the money they spent on the cardboard box packaging. It was white with multi coloured images all over it.
If you look at the box Barbie loves Mac come in it was similar to M.A.C's usual packaging black with a pink Barbie head on it. It costs extra money for different colours etc when printing these things.
If M.A.C had spent less money on T-shirts, Scarfs and Dolls when releasing Fafi, they may have been able to afford imprinted fafi goods.
I would say M.A.C has a yearly budget and to put the Dame Edna collection out without 'stickers' instead with imprinted cosmetics would be pushing it.
If you look at the box its coloured, has pictures on it and by the looks of it, is a shiny, metallic cardboard which would not have been cheap!
This is why I think they have cut corners on the cosmetics and simply used 'stickers' instead on imprinted pictures.
Which is really annoying BTW!
That's just my 2 cents
