This is one of those Chanel nail colors that must have been released at least 2-3 times. Chanel does do variations of similar soft pinks quite often as well, so I wouldn't try too hard to track this color down actually.
#495 Mica Rose is a soft pink that goes relatively opaque after 2 coats. It's not completely opaque, but it does have a certain creaminess to the coverage once with 2 coats. It has tiny pink and silvery shimmers throughout. However, not enough to make it frosty nor metallic.
Overall rating 3.5/5.
Color is not all that original, and the wear does seem a bit weak- sometimes it just completely flakes off in 3 days, even with my normal Seche vite topcoat and Orly bonder base coat.
