I really think these might be the most useful palettes ever; I was sent mine by a US friend. It's magnetised, so it holds any metal pan securely, and it has no dividers so you can put in pans of varying shapes and sizes. This one has a mixture of MAC, Trish McEvoy and starsmakeuphaven pans in it, and still plenty of space left in it. There is also a smaller size that's perfect for holding a few products to sling in a make up bag.
The website is here - I'm not sure if they ship internationally, but if they don't lets hope they start soon!
