bareMinerals The Mix Master Eyeshadow Palette ($48.00, now $34.00, for 12 x 0.05 oz. / 0.60 oz. total) consists of twelve READY eyeshadows inside a medium-thick, plastic palette. The palette contains a palette within it--a 3-eyeshadow palette that slides out of the larger palette. You can pop in and out your favorite shades to take with you as a trio, rather than the whole kit 'n' caboodle, should you desire. The trio also holds a travel-sized, double-ended brush. Generally, I get between ten and twelve hours of wear (no primer) with bareMinerals' formula--some of the sheerer ones that have a drier texture will show fading before ten hours (usually after eight or so).
