This product, the Naked3 Eyeshadow Palette, is a great investment for a few reasons:
1. It caters to a variety of eye colors
2. Has daytime and nightime shadow options
3. Is great for mixing
4. Will last you a long, long time
5. Has every finish you could need: mattes, pearls and metallics
The palette is $54 so yes, it is on the pricier end. This item was actually gifted to me last Christmas so I lucked out, but I still think it is worth the money to virtually not have to purchase another eyeshadow for the next few years.
