Not cheap - but worth it. When I was in school this was the product I most lusted after. Being a grown up now, these are pretty much the only shadows I use and come back to. I always use them for nights out. They are silky, pretty colour dense, and wear well. I love the shades and have about 2-3 palettes... and these are my products which I am most loathe to throw out so one is older than 5 years. It lasts because you need so little when you apply it - great quality!

I cheat with these shadows and use an angle brush to apply them wet as an eyeliner as well. The trick is to always have a very clean brush to not contaminate the shadow, and to always wet the same small section of your palette (so that you keep the shadow's texture when you apply it as a powder)

Great quality. Lasts all day. Highly recomend it. You can definitely see the difference between this and cheap eye shadows.

I'm a big fan of Christian Dior, I use many of there products.
One of my favorite has to be the eye Shadows.
I own 2 different color palettes and wear them every single day!
The color pigments are so strong that you put it on in the morning and it will last you all day long. You don't have to use a lot either.
When I tried other products, I found that I had to apply a few coats of eye shadow to get the effect that I wanted, and then my eyes would start to burn and water. With Dior I never had that problem.
It might be a little pricey but you have to remember that you pay for 5 different colors!
They even come with a booklet with suggestions on how and where to apply the product. It's great for people who do not know how to blend 3-4 colors at once.
