As Amarixe said these are a very similar texture to the MAC Paint Pots.
I have the colours 'On and on bronze' and 'Permanent Taupe'. These are the exact same colours as the ones in America they have just changed the names.
On and on bronze is a beautiful bronze which really suits my blue eyes and permanent taupe is a great matte cream eyeshadow which makes a lovely grey smokey eye.
As for wearing for 24h I've not actually tried but they certainly last all day! I only have a teeny tiny bit of creasing but nothing unbearable.
Overall I love these shadows and so glad they came to the UK!
Have you picked up any of these?
