Sea Glass is a pale, silvery pewter with subtle, warm undertones and a pearly sheen. It had nearly opaque pigmentation--not at all sheer was the finish was described--that was soft, smooth, and blendable on the lid. It wore well for six and a half hours on me before fading noticeably.
Sheer, lightly pearlized shadow, which can also be used as a highlighter shade under the browbone. Comes in this sleek, flip-top compact that can be used individually or assembled into palettes (sold separately).
