I have a couple of those - in Or Desir, Petale de Glace and Prune Nocturne.
They are pretty good, but it depends what you're looking for.
I've mainly used Or Desir and Petal de Glace. They are quite sparkly (fine sparkle, not big chunks of glitter) and not massively pigmented. They last well on the skin.
The Prune Nocturne one takes a bit of work to apply if you want more than a wash of colour. I usually apply cream shadows with brushes, but I find it difficult with these ones.
They're good for a wash of colour, but I tend to reach for other products if I want more colour. I tend to mix the Or Desir and the Petal de Glace as the gold one is too yellow for me and the Petal one is a tad too pink.
I've heard really good things about the Maybelline Colour Tattoos, but I haven't tried them. I'd probably go for them over the Bourjois ones next time.
