That powder is in a metal pan, right? Or is it directly in the plastic casing?
If it is in the pan, use a hairdryer to loosen the glue on the bottom (that is holding the pan in) and a needle to pry out the pan carefully. You could then make your own e/s palette using an empty CD case (I got this idea from another thread on this website, just do a search) and start your own 'singles' eye and face palette that you can put your lone products that once came in other palettes or in a bulky package.
If it is in the plastic pan, clean out the other two pans completely, removing all excess powder. You can then put a bit of lipstick or lip balm in each pan, so that you have a portable palette of your own. Be sure to use a hairdryer to get the lipstick or balm softened enough to melt into the pans.
HTH!
