MAC Double Feature Eyeshadow Duos ($25.00 for 0.09/0.10 oz.) are pre-filled with nameless eyeshadows. Some of the duos contain 0.09 oz. while others contain 0.10 oz. From the ones I have, Double Feature #5 and #8 contain 0.10 oz., while the others contain 0.09 oz. The four featured in this post are: Double Feature 5 (pale frosty peach / dark brown with green pearl), Double Feature 6 (light grey taupe / mid-tone bronze), Double Feature 7 (bright fuchsia / cool black), and Double Feature 8 (mid-tone orange / deep navy). Once I can purchase #7, I will update this post with a review and photos/swatches for it.
