While we don't know what the shades inside will look like, I can say with certainty based on hints that the product itself will look like this on the inside. Morphe while known for affordable, quality cosmetics is not known for their packaging. Why? Because all their products are uniform. The boxes may have some designs when it's a special item but take the box away and all the palettes are slim black cases with white lettering on it. And the format is always the same. So since she said she's releasing a 9 shade highlighter palette and posted a sneak peek with square pans then this is what it will look like since Morphe just recently released some new palettes that feature the same design. Those are large pans so they're not skimping on product either. This will definitely be a hot ticket item so don't miss out because I am positive this will sell out especially given how popular highlighters are right now.
