Bought this two beautiful Becca highlighters in a Sephora store in Barcelona.
Opal is the Name of the little creamy an little pressed highlighters(both toghether cost 20 Euros).
I would reccomand them to you before you buy the "big one's" cause all becca highlighters are very high pigmented with lot of glitter and not everyone wants to look like a mirror ball
I think "OPAL" looks in comparison to "CPOP" more silver.
If i I go out, I love wearing Becca highlighters. And you?
