For mine, it was pretty hit-or-miss, which ones will hold together and which ones will crumble. For instance, just about all of my Cory shadows hold together nicely....except for the Black liner. That one crumbled all over the place. And with my SheSpace colors, they all held together well except for a couple of the orangey-gold shades that crumbled! So it's hard to say how they'll do.
