Yes, it fits my MAC palettes!!!
It's a great product.  Great idea and it fits my MAC double sided palettes perfectly which is the whole reason behind the purchase.  The double palette is too snug for the top and bottom slots but I just put my single palette in those.  I've been looking for &quot;something to organize&quot; them for so long and was excited that alegory came out with them.  I have their lipstick and lipgloss organizers.  Same heavy and durable acrylic.
