The only Stila eye product I had ever used was the Shadow Pot in lily (which is a great eye mousse, by the way) so I did not know what to expect when I ordered the Eye Shadow Duo from Sephora. The shadow is sold separately from the refillable compact so I ordered the compact, as well.
The Eye Shadow Duo in Seafoam is a pretty forest green shadow coupled with a light, yellow-green shadow. The powder is fine, containing sparkling pearls that emit a subtle shine. The shadow is fairly pigmented and buildable for a more dramatic look. When I applied the shadow with a Shu Uemura brush, I found it to be a little bit crumbly. Some of the powder also fell into my eyes and I wonder if this would have happened if I had used a sponge-tip brush instead. There have been complaints that the eye shadow duos do not fit into the refillable compact but Sea Foam fits fine. The shadows have a magnetic base that sticks to the bottom of the compact, keeping them in place.
