As a companion to the Z-Palette (which holds 9 shadows) or all on its own – the Twosie provides a compact shadow storage option with a mirror and shadow applicator. You can easily swap out eyeshadows since they are held in the case by magnets. Get more than one to configure your own “travel duos”. This is my nighttime palette, this is my day time palette. Slip them in your purse for effortless application!
