So, I dont know any dimensions of the MUFE palette but I believe the XL palette holds 28+. I originally purchased the large Z- palette to store mine because Sephora is constantly out of stock of the MUFE palette and I dont have a MUFE boutique near me. I finally got my hands on the MUFE palette(kicking myself for not buying two) one day when it snuck back in stock. The MUFE palette is a better value and more functional than the Z-palette even though its not as cute. With the Z- palette, I was forcing my 15 shadows in and the magnet is not as strong and sturdy as the MUFE which is bothersome when I want to travel, especially since the shadows are so creamy and susceptible to so many dents and nicks. Also, you get a wayyy better value for the MUFE palette. The MUFE palette was $14, holds almost double the Z- palette which is $20 and is much sturdier. The only drawback to the MUFE palette for me is the fact that because it holds more, its a little heavier and bigger which isnt a deal breaker, its just not as attractive on my vanity.
