1 - Remove the eyeshadow from the single-shade compact by sticking the end of a paperclip in the hole in the back of the case.
2 – Insert the eyeshadow into the empty palette in one of the three available spaces. The magnet on the bottom the eyeshadow attaches to the magnet inside the palette.
3 - The same palette can be used for endless colour combinations. Just remove any colours that you do not want in the palette and store them in the original single-shade compacts.
