Today I was surprised to see that they've put out these Studio Beauty on the Go Palettes. They are basically a Studio version of their Custom Elements compact.
Each Palette has 10 eyeshadows, 2 lipcolors, and a blush or bronzer. There are currently 10 different individual palettes for $3 each.
ELF then also sells storage cases that can hold either 1, 3, or 6 of the palettes.
