Eyeshadow doesn't get less complicated than this. You can use either shade of each duo on its own, or together, using the satin shade as a liner or base, and then applying the glitter shade on top.Siri, Norge
There are three innovations present here, really. The first is the spnge-tipped applicator - it actually works and minimizes fall-out. I've hardly had any, and I've got two of these thus far, as well as having had the privilege of applying some of the shades to friends. The second is the dry formula of the satin shades that applies super-pigmented and creamy. The third is the glitter shades - although #2 and #4 are shimmers - that feels creamy yet applies dry and, as previously mentioned, has hardly any fall out. At all.
Some might be intimidated by the bright colours, but most of the glitters applies sheer, with only the particles of glitter creating an interesting overlay-effect that catches the light beautifully.
If you're on the go, and yuo need to travel light, or you're just in the market for something to get you out of your rut, OR if you want someplace to start with eye makeup - This is your new best friend.
Note: My impressions are based on use with primer.
