Rather than a preset palette with colors chosen for you, with the Renzoe Box you can combine brands, products and shades of YOUR choice into a single palette. Say, for example, you use foundation by Lancôme, blush by NARS, and eyeshadow by MAC. Now you can have them all in one palette! With the preset kits you cannot customize with different brands and with precisely the types of products you want.
Also, preset palettes do not replace the makeup bag because it is just a palette. Whereas Renzoe Box has storage for brushes and other items, so it becomes a simplified, organized version of your makeup bag!
