I think some of the packaging has really declined in quality - for example the palettes with eye and lip colours from the early 00s were really nice quality and I do still have one that has lasted amazingly well! The bullet lipsticks were lovely too, but the new lipstick packaging is pathetic and totally puts me off even trying the stuff.
I'm not sure about the single eyeshadows, the old style tins are a pain to open and close, but the current design is a bit "plasticky".
Also agree about the PP, you cannot get that last bit out!
I'll forgive them though, as long as they keep making 24/7
