I looked on Rimmel's UK and JP website and neither had an eyeshadow palette that looked like the one she posted, but the crown looks like their logo. Maybe it's only available in Japan?
This is the palette they used in her promo picture posted by Lizzy:

And the lip plumper is here, I think it's only available in Japan because it wasn't on the UK website.
