Should have read the measurements more closely [SEP] This will not fit a standard sized shadow palette (think Too Faced Chocolate Bar, Sweet Peach, ABH Modern Renaissance etc...).  Also not deep enough for the square ELF face palettes -- they stick out way too far when the organizer is standing up.  Also not wide enough for the smaller Too Faced tin shadow palettes (Cat Eyes, PBJ, Boudoir Eyes etc...) to fit between the dividers.  So, with that being said, it's not much use to me but I didn't want to go through any return hassles, so it's holding some single blush and highlighter compacts right now.  I don't recommend unless you have something very specific that will fit the dimensions.  It is a nice quality item...just wish it would actually fit a palette.
