Build your own palette

I love everything about single shadows. Looking through a brand's offerings, hunting for swatches from others, rearranging them, etc.

-For eyeshadow, I know of Lethal Cosmetics! Their site has a very cool palette building function.

-For overall face, I know of Salt NY ("clean" but not extreme in price, doesn't try to lean into the whole clean thing). They have chic cases and you also mix and match on their site.

Does anyone know of other indie brands that let you build your own palette like this?
