Review (5/5): Get this one!
I don't know why I didn't think of getting this sooner. Clear blocks slide in and out. Having this makes me want to collect more palettes so I can display them!
TIP: If you're going to have it standing upright, it will fit and carry the narrower palettes such as the Naked palettes, ABH Modern Romance, and others that are similar size or smaller. If you have squarer palettes like the ABH glow kits and contour kit, morphe palette, etc, you will need to have the organizer laying flat, otherwise your palettes will fall out with the organizer standing upright.
