For reference: NW10 (up to NW13 when "tanned"), dark brown eyes, combo skin leaning oily in the summer & dry in the winter.
I have this in Teakwood & Star, and I plan on buying more shades soon. These are really lovely, at least the shades I have. Pigmented & soft, AND they stay pristine all day for me until I remove my mu (all day being around 6am - 11pm - that's 17 hours!!), even on my watery waterline (usually I get some smudging/transfering, especially near the inner corner/tear duct, the whole line will smudge & move down).
Teakwood is a matte darker reddish-brown color with maybe hints of burgundy, it has at least much red as brown but is definitely very toned down. Very unusual shade for an eyeliner, drugstore or HE. At first I was a little concerned that the redness of Teakwood might make my eyes look bloodshot and sick, but to my surprise Teakwood looks very natural & flattering. Maybe because there is naturally some redness in my eye area and Teakwood plays on that. But this red-toned brown looks much more natural & flattering than straight-up brown eyeliner. Some people didn't even realize I had eyeliner on, just thought I had naturally defined eyes. :D I've been using this regularly for ~3 months now and for sure will rebuy when I run out.
Star is a slightly frosty/shimmery off-white. It's nice for the inner corner but it's sometimes not as opaque as I'd like. In general, I get the feeling that it's not as nice as Teakwood - Star is less pigmented, slightly "greasier", doesn't last AS long, etc. It's still a very decent eyeliner, but I would not repurchase.
I'd give Teakwood 5/5 and Star a 3.7/5. I gave an overall rating of 5 because Teakwood is so awesome and Star is certainly decent quality, I just personally prefer using eyeshadow for inner corner highlighting instead.
