New MAC Pigment Jars

So, I looked at the MAC website recently and saw that the change in the pigment jar which has been hotly debated over in the US now seems to have made its way over here.

The new jar, pictured on the left, is labelled 4.5g, whereas the old jar was labelled 7.5g. As we all know, the density differences between pigments mean that you often get slightly more or less depending on the shade, but still, that's a fairly large drop in labelled weight with no corresponding drop in price.

Temptalia has done a useful comparison of the amount of pigment in the old vs new jar for the same colour, which includes lots of maths, and concludes that while the new jars do contain less, it's not a whole 3g less.

While I think it's a bit cheeky to decrease the size so noticeably without reducing the price, I'm not really all that fussed - I can't imagine ever getting to the bottom of a jar to miss the extra grams. What do you think?
